It is characterized by NMR and vibrational spectroscopy and the crystal structure analysis. [(CH₃)₄N]⁺[SO₂N₃]^– crystallizes in the monoclinic space group P2₁/c with a = 551.3(1) pm, b = 1095.2(1) pm, c = 1465.0(1) pm, β = 100.63(1)°, and four formula units in the unit cell. The crystal structure possesses a strong S–N interaction between the N^3– anions and the SO₂ molecules. The S–N distance of 200.5(2) pm is longer than a covalent single S–N bond. The structure is compared with ab initio calculated data. Furthermore an adduct of tetrametylammonium cyanate and sulfur dioxide is reported. It is characterised by NMR and vibrational spectroscopy. The structure is calculated by ab initio methods.     

A Nickel(II) Nitrite Based Molecular Perovskite Ferroelectric

The X‐site ion in organic–inorganic hybrid ABX₃ perovskites (OHPs) varies from halide ion to bridging linkers like HCOO^?, N₃^?, NO₂^?, and CN^?. However, no nitrite‐based OHP ferroelectrics have been reported so far. Now, based on non‐ferroelectric [(CH₃)₄N][Ni(NO₂)₃], through the combined methodologies of quasi‐spherical shape, hydrogen bonding functionality, and H/F substitution, we have successfully synthesized an OHP ferroelectric, [FMeTP][Ni(NO₂)₃] (FMeTP=N‐fluoromethyl tropine). As an unprecedented nitrite‐based OHP ferroelectric, the well‐designed [FMeTP][Ni(NO₂)₃] undergoes the ferroelectric phase transition at 400 K with an Aizu notation of 6/mmmFm, showing multiaxial ferroelectric characteristics. This work is a great step towards not only enriching the molecular ferroelectric families but also accelerating the potential practical applications.     

Reaktionsprodukte von S7NH mit Nickel- und Kupfersalzen Darstellung und Struktur der Komplexe [(CH3)4N][Ni(S3N)(CN)2], [(C6H5)4As][Cu(S3N)2] und [(C6H5)4As][Cu(S3N)CI]

Metal Sulfur Nitrogen Compounds 18. Reaction Products of S₇NH with Nickel and Copper Salts. Preparation and Structures of the Complexes [Ch₃₄N][Ni(S₃N)(CN)₂], [(C₆H₅)₄As][Cu(S₃N)₂], and [(C₆H₅)₄AS][Cu(S₃N)Cl]. In the presence of MOH (M = K, [(CH₃)₄N]), S₇NH reacts with Ni(CN)₂ to yield, besides the three-nuclear complex M[(S₃NNi)₃S₂], the new mononuclear complex M[Ni(S₃N)(CN)₂]. The [(CH₃)₄N]⁺ salt is monoclinic, C2/m, a = 19.303(9), b =6.941(3), c=16.309(10) Å, β = 144.51⁰(2), Z = 4. The [Ni(S₃N)(CN)₂]- anion is planar, Ni being coordinated by one S₃N^? chelate ligand and by two CN^? ions. From the reaction of CuCI₂, S₇NH, and [Ph₄As]OH result the salts [Ph₄As][Cu(S₃N)₂] or [Ph₄As][Cu(S₃N)Cl], depending on the reaction conditions. [Ph₄As][Cu(S₃N)₂] is triclinic, P&1macr;, a = 7.073(3), b = 11.742(4), c = 16.439(6) Å α = 91.08°(3), β = 99.01°(3), γ = 91.58°(3), Z = 2. Two S₃N^? chelate ligands coordinate to Cu^I in a distorted tetrahedral arrangement. [Ph₄As][Cu(S₃N)Cl] is monoclinic, C2/c, a = 17.174(6), b = 13.650(5), c = 21.783(5) Å β = 100.45°(2), Z = 8. Cu^I is coordinated by one S₃N^? chelate ligand and one C1^?, resulting in a trigonal planar environment.     

3‐Rhoda‐1,2‐diazacyclopentanes: A Series of Novel Metallacycle Complexes Derived From CN Functionalization of Ethylene

Rh‐containing metallacycles, [(TPA)Rh^III(κ²‐(C,N)‐CH₂CH₂(NR)₂‐]Cl; TPA=N,N,N,N‐tris(2‐pyridylmethyl)amine have been accessed through treatment of the Rh^I ethylene complex, [(TPA)Rh(η²‐CH₂CH₂)]Cl ([ 1 ]Cl) with substituted diazenes. We show this methodology to be tolerant of electron‐deficient azo compounds including azo diesters (RCO₂N?NCO₂R; R=Et [ 3 ]Cl, R=iPr [ 4 ]Cl, R=tBu [ 5 ]Cl, and R=Bn [ 6 ]Cl) and a cyclic azo diamide: 4‐phenyl‐1,2,4‐triazole‐3,5‐dione (PTAD), [ 7 ]Cl. The latter complex features two ortho‐fused ring systems and constitutes the first 3‐rhoda‐1,2‐diazabicyclo[3.3.0]octane. Preliminary evidence suggests that these complexes result from N–N coordination followed by insertion of ethylene into a [Rh]?N bond. In terms of reactivity, [ 3 ]Cl and [ 4 ]Cl successfully undergo ring‐opening using p‐toluenesulfonic acid, affording the Rh chlorides, [(TPA)Rh^III(Cl)(κ¹‐(C)‐CH₂CH₂(NCO₂R)(NHCO₂R)]OTs; [ 13 ]OTs and [ 14 ]OTs. Deprotection of [ 5 ]Cl using trifluoroacetic acid was also found to give an ethyl substituted, end‐on coordinated diazene [(TPA)Rh^III(κ²‐(C,N)‐CH₂CH₂(NH)₂‐]⁺ [ 16 ]Cl, a hitherto unreported motif. Treatment of [ 16 ]Cl with acetyl chloride resulted in the bisacetylated adduct [(TPA)Rh^III(κ²‐(C,N)‐CH₂CH₂(NAc)₂‐]⁺, [ 17 ]Cl. Treatment of [ 1 ]Cl with AcN?NAc did not give the Rh?N insertion product, but instead the N,O‐chelated complex [(TPA)Rh^I ( κ²‐(O,N)‐CH₃(CO)(NH)(N?C(CH₃)(OCH?CH₂))]Cl [ 23 ]Cl, presumably through insertion of ethylene into a [Rh]?O bond.     

An A‐Site Mixed‐Ammonium Solid Solution Perovskite Series of [(NH2NH3)x(CH3NH3)1−x][Mn(HCOO)3] (x=1.00–0.67)

The A‐site mixed‐ammonium solid solutions of metal–organic perovskites [(NH₂NH₃)_x(CH₃NH₃)_1?x][Mn(HCOO)₃] (x=1.00–0.67) exhibit para‐ to ferroelectric diffuse phase transitions with lowered transition temperatures from x=1.00 to 0.67. These properties are due to the decreased framework distortion and polarization in their low temperature ferroelectric phases caused by the increased CH₃NH₃⁺ concentration.     

Beiträge zur Chemie der Alkylverbindungen von Übergangsmetallen. XXXIV. Darstellung und Eigenschaften von 3-(N,N-Dialkylamino)-propylmangan-Verbindungen

Contributions to the Chemistry of Transition Metal Alkyl Compounds. XXXIV. Synthesis and Properties of 3-(N,N-dialkylamino)propyl Manganese Compounds MnCl₂ reacts with lithium organyls of the type R₂N(CH₂)₃Li with formation of definite organomanganese complexes. The pure [(CH₃)₂N(CH₂)₃]₂Mn, [(C₂H₅)₂N(CH₂)₃]₂Mn, [(CH₂)₅N(CH₂)₃]₂Mn and the complexes [(CH₃)₂N(CH₂)₃]₂Mn · LiCl and Li{Mn[(CH₂)₃N(CH₃)₂]₃} · 1,5 THF were isolated. [(CH₃)₂N(CH₂)₃]₂Mn · 2 Li(acac) was obtained as a result of reactions of Mn(acac)₂ and Mn(acac)₃ with the corresponding lithium organyl. The σ-organomanganese(II) derivatives were characterized in detail by elementary analysis, molecular weight determination, ESR- and IR-spectra, conductivity measurements and the magnetic moments.     

Synthesis,Characterization, and Crystal Structures of [N(CH3)4]2[B12H12] and [N(CH3)4]2[B12H12] · CH3CN

Bis(tetramethylammonium) dodecahydrododecaborate, [(CH₃)₄N]₂[B₁₂H₁₂], and bis(tetramethylammonium) dodecahydrododecaborate acetonitrile, [(CH₃)₄N]₂[B₁₂H₁₂] · CH₃CN, were synthesized and characterized via Infrared, ¹H and ¹¹B NMR spectroscopy. [(CH₃)₄N]₂[B₁₂H₁₂] crystallizes isopunctual to the alkali metal dodecaborates. The crystal structure of [(CH₃)₄N]₂[B₁₂H₁₂] · CH₃CN was determined from single crystal data and refined in the orthorhombic crystal system (Pcmn, no. 62, a = 898.68(8), b = 1312.85(9) c = 1994.5(1) pm, R(|F| , 4σ) = 5.9%, wR(F²) = 18.3%). Here, the geometry of the dodecaborate anion is that of an almost ideal icosahedron, less distorted than most other dodecaborates known. By low‐temperature Guinier‐Simon diffractometry phase transitions were detected for [(CH₃)₄N]₂[B₁₂H₁₂] and [(CH₃)₄N]₂[B₁₂H₁₂] · CH₃CN at –70 and –15 °C, respectively.     

The Molybdenum(V) and Tungsten(VI) Oxoazides [MoO(N3)3], [MoO(N3)3⋅2 CH3CN], [(bipy)MoO(N3)3], [MoO(N3)5]2−, [WO(N3)4], and [WO(N3)4⋅CH3CN]

A series of novel molybdenum(V) and tungsten(VI) oxoazides was prepared starting from [MOF₄] (M=Mo, W) and Me₃SiN₃. While [WO(N₃)₄] was formed through fluoride–azide exchange in the reaction of Me₃SiN₃ with WOF₄ in SO₂ solution, the reaction with MoOF₄ resulted in a reduction of Mo^VI to Mo^V and formation of [MoO(N₃)₃]. Carried out in acetonitrile solution, these reactions resulted in the isolation of the corresponding adducts [MoO(N₃)₃?2 CH₃CN] and [WO(N₃)₄?CH₃CN]. Subsequent reactions of [MoO(N₃)₃] with 2,2′‐bipyridine and [PPh₄][N₃] resulted in the formation and isolation of [(bipy)MoO(N₃)₃] and [PPh₄]₂[MoO(N₃)₅], respectively. Most molybdenum(V) and tungsten(VI) oxoazides were fully characterized by their vibrational spectra, impact, friction and thermal sensitivity data and, in the case of [WO(N₃)₄?CH₃CN], [(bipy)MoO(N₃)₃], and [PPh₄]₂[MoO(N₃)₅], by their X‐ray crystal structures.

Synthesis and Crystal Structure of the Heterobimetallic Diorganotindichloride (FcN, N)₂SnCl₂ (FcN, N^—: (η⁵‐C₅H₅)Fe{η⁵‐C₅H₃[CH(CH₃)N(CH₃)CH₂CH₂NMe₂]‐2}^—) The heterobimetallic title compound [(FcN, N)₂SnCl₂] ( 1 ) was obtained by the reaction of [LiFcN, N] with SnCl₄ in the molar ratio 1:1 in diethylether as a solvent. The two FcN, N^— ligands in 1 are bound to Sn through a C‐Sn σ‐bond; the amino N atoms of the side‐chain in FcN, N^— remain uncoordinated. The crystals contain monomeric molecules with a pseudo‐tetrahedral coordination at the Sn atom: Space group P2₁/c; Z = 4, lattice dimensions at —90 °C: a = 9.6425(2), b = 21.7974(6), c = 18.4365(4) Å, β = 100.809(2)°, R1_obs· = 0.051, wR2_obs· = 0.136.     

Die Kristallstruktur von cis‐ und trans‐N‐iso‐Propylamidodimethylindium, [(CH3)2In‐N(H)iC3H7]2

The Crystal Structure of cis‐ and trans‐N‐iso‐Propylamidodimethyl Indium, [(CH₃)₂In‐N(H)ⁱC₃H₇]₂ According to the X‐ray structure determination [(CH₃)₂In‐N(H)ⁱC₃H₇]₂ (prepared from InMe₃ (Me = CH₃) and H₂NⁱPr (ⁱPr = CH(CH₃)₂) crystallizes in the monoclinic space group P2₁/n with 3 dimeric trans as well as 3 dimeric cis isomers per unit cell. The centrosymmetric form has a planar In₂N₂ core with In—N bonds of 222.1(4) and 222.9(5) pm, respectively, the skeleton of the cis isomer with In—N bonds of 221.4(4) pm is slightly folded (13.7°). Some ¹H, ¹³C NMR, IR, and Raman data are reported.     

EPR of gamma irradiated (CH3)3NHClO4, (CH3)3NHBF4 and [(CH3)4N]2ZnCl4 single crystals

Gamma irradiation damage centres in (CH₃)₃NHClO₄, (CH₃)₃NHBF₄ and [(CH₃)₄N]₂ZnCl₄ were investigated by electron paramagnetic resonance spectroscopy at room temperature. The centres were found to be (CH₃)₃N^+. and the hyperfine structure parameters for methyl protons and the nitrogen nucleus were determined. The results indicated that the (CH₃)₃N^+. radical wholly performs reorientational motions around its C_3v axis in addition to the reorientatonal motions of the methyl groups around their C_3v axes. These results were compared with the earlier studies on (CH₃)₃N^+. radical and discussed. Low temperature measurements on the first two of the title compounds were assessed.     

An Unusual Phase Transition Driven by Vibrational Entropy Changes in a Hybrid Organic–Inorganic Perovskite

The driving forces for the phase transitions of ABX₃ hybrid organic–inorganic perovskites have been limited to the octahedral tilting, order–disorder, and displacement. Now, a complex structural phase transition has been explored in a HOIP, [CH₃NH₃][Mn(N₃)₃], based on structural characterizations and ab initio lattice dynamics calculations. This unusual first‐order phase transition between two ordered phases at about 265 K is primarily driven by changes in the collective atomic vibrations of the whole lattice, along with concurrent molecular displacements and an unusual octahedral tilting. A significant entropy difference (4.35 J K^?1 mol^?1) is observed between the low‐ and high‐temperature structures induced by such atomic vibrations, which plays a main role in driving the transition. This finding offers an alternative pathway for designing new ferroic phase transitions and related physical properties in HOIPs and other hybrid crystals.     

The Vanadium(V) Oxoazides [VO(N3)3], [(bipy)VO(N3)3], and [VO(N3)5]2−

Vanadium(V) oxoazide [VO(N₃)₃] was prepared through a fluoride–azide exchange reaction between [VOF₃] and Me₃SiN₃ in acetonitrile solution. When the highly impact‐ and friction‐sensitive compound [VO(N₃)₃] was reacted with 2,2′‐bipyridine, the adduct [(bipy)VO(N₃)₃] was isolated. The reaction of [VO(N₃)₃] with [PPh₄]N₃ resulted in the formation and isolation of the salt [PPh₄]₂[VO(N₃)₅]. The adduct [(bipy)VO(N₃)₃] and the salt [PPh₄]₂₃[VO(N₃)₅] were characterized by vibrational spectroscopy and single‐crystal X‐ray structure determination, making these compounds the first structurally characterized vanadium(V) azides.     

Inorganic-organic hybrid compounds: hydrothermal synthesis and characterization of a new three-dimensional metal tetraphosphonate Mn[(HO3PCH2)N(H)(CH2)4(H)N(CH2PO3H)2]

The new manganese tetraphosphonate, Mn[(HO₃PCH₂)₂N(H)(CH₂)₄(H)N(CH₂PO₃)₂] (1) was hydrothermally synthesized from MnCl₂ and N,N,N′,N′-tetrametylphosphono-1,4-diaminobutane, (H₂O₃PCH₂)₂N-(CH₂)₄-N(CH₂PO₃H₂)₂. The structure was determined from single-crystal X-ray diffraction data (Mn[(HO₃PCH₂)₂N(H)(CH₂)₄(H)N(CH₂PO₃)₂], monoclinic, P2₁/a, with a=9.6663(1), b=9.2249(2), c=10.5452(1) pm, β=105.676(1)°, V=905.35(3)×10⁶ pm, Z=2, R₁=0.051, wR₂=0.109 (all data). The structure contains the zwitter ions [(HO₃PCH₂)₂N(H)-(CH₂)₄-(H)N(CH₂PO₃)₂]²⁻ and is built from alternating corner-linked [MnO₆] and [PO₃C] polyhedra forming a two-dimensional net of eight-rings. These layers are connected to a pillared structure by the diaminobutane groups. Magnetic susceptibility data confirms the presence of Mn²⁺ ions. Thermogravimetric measurements show a stability of 1 up to ∼290°C. Between 290°C and 345°C a one-step loss of ∼7.0% is observed, and above 345°C the continuous decomposition of the organic part of the structures takes place.

Studies of Polyhalides. 22. On Dimethyldiphenylammoniumpolyiodides (Me₂Ph₂N)I_n with n = 3, 13/3, 6, and 8: Preparation and Crystal Structures of a Triiodide (Me₂Ph₂N)I₃, Tridecaiodide (Me₂Ph₂N)₃I₁₃, Dodecaiodide (Me₂Ph₂N)₂I₁₂, and Hexadecaiodide (Me₂Ph₂N)₂I₁₆ The new compounds [(CH₃)₂(C₆H₅)₂N]I₃, [(CH₃)₂(C₆H₅)₂N]₃I₁₃, [(CH₃)₂(C₆H₅)₂N]₂I₁₂ and [(CH₃)₂(C₆H₅)₂N]₂I₁₆ have been prepared by the reaction of dimethyldiphenylammonium iodide [(CH₃)₂(C₆H₅)₂N]I with iodine I₂ in ethanol. Their crystal structures have been determined by single crystal X-ray diffraction methods. The structure of the triiodide may be described as a layerlike packing of pairs of nearly linear symmetric anions and tetraedral cations. The tridecaiodide forms zig-zag chains of iodide ions and iodine molecules with the iodide ion also weakly coordinated by two pentaiodide groups. The dodecaiodide is built from two pentaiodide-groups, which are bridged by an iodine molecule and connected with secondary bonds forming double chains. The hexadecaiodide ion forms layers built up from two heptaiodide groups and one iodine molecule. Thus the dimethyldiphenylammonium cation stabilizes a unique series of polyiodides of extraordinary composition and structure.     

An unusual partial occupancy of labile chloride and aqua ligands in cocrystallized isomers of a nickel(II) complex bearing a tripodal N4‐donor ligand

A novel Ni²⁺ complex with the N₄‐donor tripodal ligand bis[(1‐methyl‐1H‐imidazol‐2‐yl)methyl][2‐(pyridin‐2‐yl)ethyl]amine (L), namely, aqua{bis[(1‐methyl‐1H‐imidazol‐2‐yl‐κN³)methyl][2‐(pyridin‐2‐yl‐κN)ethyl]amine‐κN}chloridonickel(II) perchlorate, [NiCl(C₁₇H₂₂N₆)(H₂O)]ClO₄ or [NiCl(H₂O)(L)Cl]ClO₄ ( 1 ), was synthesized and characterized by spectroscopic and spectrometric methods. The crystal structure of 1 reveals an interesting and unusual cocrystallization of isomeric complexes, which are crystallographically disordered with partial occupancy of the labile cis aqua and chloride ligands. The Ni²⁺ centre exhibits a distorted octahedral environment, with similar bond lengths for the two Ni—N(imidazole) bonds. The bond length increases for Ni—N(pyridine) and Ni—N(amine), which is in agreement with literature examples. The bond lengths of the disordered labile sites are also in the expected range and the Ni—Cl and Ni—O bond lengths are comparable with similar compounds. The electronic, redox and solution stability behaviour of 1 were also evaluated, and the data obtained suggest the maintenance of structural integrity, with no sign of demetalation or decomposition under the studied conditions.     

Synthesis and Characterization of Tricarbastannatranes and Their Reactivity in B(C6F5)3‐Promoted Conjugate Additions

The synthesis and characterization of a series of tricarbastannatranes, in the solid state and in solution, are described.

Furthermore, the B(C₆F₅)₃‐promoted conjugate addition of alkyl‐tricarbastannatranes to benzylidene derivatives of Meldrum’s acid was investigated, and detailed mechanistic studies are presented.     

From cyclotetrasilazane [(CH3)2SiNH]4 via crystalline silicon nitride imide Si2N2NH to α-Si3N4

α-Si₃N₄ is synthesized by an ammonia thermal synthesis using a cyclic oligosilazane, [(CH₃)₂SiNH]₄, as the starting material. [(CH₃)₂SiNH]₄ reacts in the presence of ammonia at 900°C and 80 MPa pressure to give silicon nitride imide (Si₂N₂NH). Subsequently, Si₂N₂NH is converted into α-Si₃N₄ by thermal decomposition at 1500°C and 0.1 MPa nitrogen with the simultaneous loss of NH₃.     

Synthesis,Structures, and Magnetic Properties of Chiral One‐dimensional CrIII‐MnIII Heterobimetallic Complexes Based on [(Tp)Cr(CN)3]–

Two Cr^III‐Mn^III heterobimetallic compounds, [Mn((R,R)‐5‐MeOSalcy)Cr(Tp)(CN)₃ · 2CH₃CN]_n ( 1‐RR ) and [Mn((S,S)‐5‐MeOSalcy)Cr(Tp)(CN)₃·2CH₃CN]_n ( 1‐SS ) [Salcy = N,N′‐(1,2‐cyclohexanediylethylene)bis(salicylideneiminato) dianion], were synthesized by using the tricyanometalate building block, [(Tp)Cr(CN)₃]^– [Tp = tris(pyrazolyl) hydroborate] and chiral Mn^III Schiff base precursors. Structural analyses and circular dichroism (CD) spectra revealed that 1‐RR and 1‐SS are a pair of enantiomers containing a neutral cyano‐bridged zigzag chain with (–Cr–C≡N–Mn–N≡C–)_n as the repeating unit. Magnetic studies show that antiferromagnetic couplings between Cr^III and Mn^III ions occur by cyanide bridges. 1‐RR and 1‐SS present metamagnetic, spin‐canting, and antiferromagnetic order behaviors at low temperatures.

At reactions of 2 with AlBr₃ and AuCl · PPh₃ the heterobimetallic organo derivatives (FcN,N)AlBr₂ ( 3 ), (FcN,N)Au · PPh₃ ( 4 ) are formed. A detailed characterization of 2 – 4 was carried out by single crystal x‐ray analyses as well as by NMR and Mößbauer spectroscopy.
