Solvothermal Synthesis and Crystal Structures of Two Thioantimonate(V) Compounds with the [SbS4]3— Anion Acting as a Monodentate Ligand: [Mn(C6H18N4)(C6H19N4)]SbS4 and [Mn(C6H14N2)3]2[Mn(C6H14N2)2(SbS4)2]·6H2O

The two novel thioantimonate(V) compounds [Mn(C₆H₁₈N₄)(C₆H₁₉N₄)]SbS₄ ( I ) and [Mn(C₆H₁₄N₂)₃][Mn(C₆H₁₄N₂)₂(SbS₄)₂]·6H₂O ( II ) were synthesized under solvothermal conditions by reacting elemental Mn, Sb and S in the stoichiometric ratio in 5 ml tris(2‐aminoethyl)amine (tren) at 140 °C or chxn (trans‐1, 2‐diaminocyclohexane, aqueous solution 50 %) at 130 °C. Compound I crystallises in the triclinic space group P1¯, a = 9.578(2), b = 11.541(2), c = 12.297(2)Å, α = 62.55(1), β = 85.75(1), γ = 89.44(1)°, V = 1202.6(4)ų, Z = 2, and II in the monoclinic space group C2/c, a = 32.611(2), b = 13.680(1), c = 19.997(1)Å, β = 117.237(5)°, V = 7931.7(8)ų, Z = 4. In I the Mn²⁺ cation is surrounded by one tetradentate tren molecule, one protonated tren acting as a monodentate ligand and a monodentate [SbS₄]^3— anion yielding a distorted octahedral environment. In II one unique Mn²⁺ ion is in an octahedral environment of three bidentate chxn molecules and the second independent Mn²⁺ ion is coordinated by two chxn ligands and two monodentate [SbS₄]^3— units leading to a distorted octahedral surrounding. The compounds were investigated and characterized with thermal and spectroscopic methods.     

Solvothermal synthesis and crystal structure of Sb(III) and Sb(V) thioantimonates: [Mn(en)3]2Sb2S5 and [Ni(en)3(Hen)]SbS4

Thioantimonate compounds of [Mn(en)₃]₂Sb₂S₅ (1) and [Ni(en)₃(Hen)]SbS₄ (2) (en=ethylenediamine) were prepared by reaction of transition metal chloride with Sb and S₈ powders under solvothermal conditions. Compound 1 consists of discrete [Sb₂S₅]⁴⁻ anion, which is formed by corner-sharing SbS₃ trigonal pyramids. Compound 2 is composed of discrete tetrahedral [SbS₄]³⁻ anion. The compounds 1 and 2 are charge compensated by [M(en)₃]²⁺ cations, whereas in the crystal of 2 there is another counter ion of [Hen]⁺. The results of the synthesis suggest that the temperature, the concentration and the existing states of the starting materials and so on are important for the structure and composition of the final products. In addition, the oxidation-state of antimony might be related to the molar ratio of the reactants. Excess amount of elemental S is beneficial to the higher oxidation-state of thioantimonate (V). Compound 1 decomposes from 150°C to 350°C, while compound 2 decomposes from 200°C to 350°C remaining Sb₂S₃ and NiSbS as residues.     

Novel Copper(I)‐Thioantimonates(III): Solvothermal Synthesis,Crystal Structures,Thermal Stability and Magnetic Properties of (C2N2H10)0.5Cu2SbS3, (C3N2H12)0.5Cu2SbS3, and (C4N2H14)0.5Cu2SbS3

The novel copper(I)‐thioantimonates(III) (enH₂²⁺)_0.5Cu₂SbS₃ ( I ) (en = ethylendiamine), (1, 3‐DAPH₂²⁺)_0.5Cu₂SbS₃ ( II ) (1, 3‐DAP = 1, 3 diaminopropane) and (1, 4‐DABH₂²⁺)_0.5Cu₂SbS₃ ( III ) (1, 4‐DAB = 1, 4‐diaminobutane) were synthesized under solvothermal conditions reacting Sb₂S₃, CuCl₂·2H₂O, S with the amines. The compounds crystallize in the monoclinic space group P2₁/n. The primary building units are a SbS₃ trigonal pyramid and two distorted CuS₃ units. In the structures the SbS₃ pyramid is connected to six CuS₃ moieties and every S atom has bonds to one Sb atom and to two Cu atoms. Further interconnection leads to the formation of ten‐membered (10 MR) Cu₃Sb₂S₅ and six‐membered (6 MR) Cu₂SbS₃ rings. Every 10 MR is condensed to four 10 MR and four 6 MR to form a single layer within the (010) plane. Two such single layers are connected to a double layer thus forming the final [Cu₂SbS₃]^— layered anion. The [CuSbS₃]^— protonated amines are located between the layers and the interlayer spacing depends on the size and orientation of these amines. Between the Sb atom and one Cu atom a remarkable short distance of about 2.7Å is observed. At elevated temperatures the compounds decompose into CuSbS₂ and Cu₃SbS₄ suggesting a complex redox reaction. Diamagnetic susceptibilities indicate the copper(I) in the metal sulfide frameworks. All three compounds are semiconductors with intermediate band gaps of about 2 eV.     

Three New Thioantimonates(V): Solvothermal Syntheses and Crystal Structures of [M(chxn)3]3(SbS4)2·4H2O (M = Ni,Co) and [Co(dien)2][Co(tren)SbS4]2·4H2O

The three new thioantimonates(V) [Ni(chxn)₃]₃(SbS₄)₂·4H₂O ( I ), [Co(chxn)₃]₃(SbS₄)₂·4H₂O ( II ) (chxn is trans‐1,2‐diaminocyclohexane) and [Co(dien)₂][Co(tren)SbS₄]₂·4H₂O ( III ) (dien is diethylenetriamine and tren is tris(2‐aminoethyl)amine) were synthesized under solvothermal conditions. Compounds I and II are isostructural crystallizing in space group C2/c. The structures are composed of isolated [M(chxn)₃]²⁺ complexes (M = Ni, Co), [SbS₄]^3? anions and crystal water molecules. Short S···N/S···O/O···O separations indicate hydrogen bonding interactions between the different constituents. Compound III crystallizes in space group and is composed of [Co(dien)₂]²⁺ and [Co(tren)SbS₄]^? anions and crystal water molecules. In the cationic complex the Co²⁺ ion is in an octahedral environment of two dien ligands whereas in [Co(tren)SbS₄]^? the Co²⁺ ion is in a trigonal bipyramidal coordination of four N atoms of tren and one S atom of the [SbS₄]^3? anion, i.e., two different coordination polyhedra around Co²⁺ coexist in this compound. Like in the former compounds an extended hydrogen bonding network connects the complexes and the water molecules into a three‐dimensional network.     

Solvothermal Synthesis and Crystal Structure of Mn2(C5H14N2)Sb2S5: A New Member of the Mn2(L)Sb2S5 Family (L is an Organic Structure Director)

The new compound Mn₂(C₅H₁₄N₂)Sb₂S₅ (C₅H₁₄N₂ = 1,3‐diaminopentane, DAPE) was prepared under solvothermal conditions using the elements as starting materials. The compound crystallizes in the orthorhombic space group Pbca with the lattice parameters a = 12.620(3), b = 11.877(2) and c = 21.814(4) Å. The primary building units are trigonal SbS₃ pyramids and distorted MnS₆ and MnS₄N₂ octahedra. These primary building blocks are joined to form Mn₂Sb₂S₄ hetero‐cubane units which are then connected via common corners, edges and faces thus forming a second type of hetero‐cubane. The hetero‐cubanes are condensed into layers within the (001) plane. The connection mode yields ellipsoidal pores within the layers with dimensions of about 9·7.5Å. The N atoms of the structure directing amines are exclusively bound to one of the two crystallographically independent Mn²⁺ cations and they point into the pores and between the layers separating the layers from each other. The interlayer separation measures about 6.7Å. Whereas the MnS₆ octahedron shows only a moderate distortion the MnS₄N₂ octahedron is severely distorted with a remarkable long Mn‐S bond length of 2.968Å.     

Solvothermal Synthesis,Crystal Structure and Properties of a New Organic Templated Lanthanum Sulfate [C4N3H16][La(SO4)3(H2O)]

A new organic templated lanthanum sulfate [C₄N₃H₁₆][La(SO₄)₃(H₂O)] ( 1 ) has been solvothermally synthesized by using n‐butanol as solvent. The colorless block crystals were characterized by IR, TGA, ICP, and XRD. The structure was determined by single‐crystal X‐ray diffraction: Monoclinic, P2₁/c, a = 10.8878(19), b = 15.478(3), c = 9.9639(18) Å, β = 114.062(2)°, V=1533.2(5) ų, Z = 4]. Crystal structure analysis shows that the one dimensional chain of 1 consists of the LaO₉ polyhedra and the sulfate groups. Coordination water molecules link adjacent chains by using hydrogen bonds to generate 2D layers, whereas the organic amines are inserted between the layers. The formation of 1 demonstrates that solvents play an important role during the synthesis.

Two Related Porous Thioindates with T3 Clusters, (H2DAH)3In10S18·6H2O and (H2DAH)3In10S18

Two high porous thioindates with 1,6‐diaminohexane (DAH), DAH‐InS‐ 1 and DAH‐InS‐ 2 , were prepared by solvothermal reaction. Though the same T₃ supertetrahedral frameworks were reported, the cations are different. DAH is a non‐cyclic diamine and also an economical reagent for synthesis. Because of the structural difference of the structural directing agents, the dimensions of crystal cells of DAH‐InS‐ 1 and DAH‐InS‐ 2 are elongated and the total volumes for the cation and solvent are 74.6 and 72.1 % (Platon) larger relative to those reported previously. The two compounds were obtained in one reaction system by controlling the reaction time. Their structures are briefly discussed and the correlativity of crystal shape with the parameters of microstructure is discussed.

On the Flexibility of Thioantimonate Networks: Solvothermal Syntheses and Crystal Structures of Six New Thioantimonates(III) with the [Sb4S7]2− Anion

Six new thioantimonates(III) with the [Sb₄S₇]²⁻ anion were obtained under solvothermal conditions with in‐situ formed transition metal complexes as structure directors. In the two isostructural compounds [Fe(dien)₂]Sb₄S₇·H₂O ( 1 ) and [Co(dien)₂]Sb₄S₇·0.5 H₂O ( 2 ) (dien = diethylenetriamine; space group: P2₁/c) the layered [Sb₄S₇]²⁻ anion is characterized by Sb₈S₈ rings with a diameter of about 9.6·7.6Å. The cation complexes are located above and below the pores of the rings. Despite the larger size of the cation complex the network topology of the third thioantimonate [Ni(dien)(tren)]Sb₄S₇ ( 3 ) (tren = tris(2‐aminoethyl)amine; space group: P2₁/n) is similar to that of the first two compounds. In the isostructural thioantimonates [M(trien)]Sb₄S₇ (M = Zn ( 4 ); M = Mn ( 5 ); trien = triethylenetetramine; space group: ) the M²⁺ ions are fivefold coordinated by four N atoms of the amine molecule and by one S atom of the thioantimonate anion forming a MN₄S trigonal bipyramid. Sb₈S₁₆ building blocks are the central structural motifs of the anion. Two of the terminal S atoms at the periphery of the Sb₈S₁₆ units are bound to M²⁺ ions and the four remaining terminal S atoms connect adjacent Sb₈S₁₆ groups into the final [Sb₄S₇]²⁻ chain. [Ni(tren)]Sb₄S₇ ( 6 ) (space group: ) contains a one‐dimensional anionic chain. The Ni²⁺ ion has two bonds to the [Sb₄S₇]²⁻ anion which is a unique feature in the thioantimonate(III) chemistry. The NiN₄S₂ octahedron is severly distorted with one very long Ni‐S bond of 2.782(2) Å. In all compounds several short S···H distances indicate hydrogen bonding interactions.

Single crystals of Li₄(PO₂NH)₄ · 4 H₂O were obtained by dissolving LiOH and H₄(PO₂NH)₄ · 2 H₂O in water and subsequent precipitation with acetone and ethanol followed by slow evaporation of the solvents. The structure of Li₄(PO₂NH)₄ · 4 H₂O was solved by single‐crystal X‐ray methods ( (No. 2), a = 489.2(2), b = 853.2(2), c = 880.5(2) pm, α = 101.71(3), β = 102.39(3), γ = 94.88(3)°, Z = 1). The structure is composed of LiO₄ tetrahedra and (PO₂NH)₄^4? ions. The P₄N₄ rings of the anions exhibit a slightly distorted chair–1 conformation, which is supported by IR data and has been described by torsion angles, displacement asymmetry parameters and puckering parameters. Via Li⁺ ions and hydrogen bonds, the tetrametaphosphimate anions are connected forming a three‐dimensional network.     

New Thioantimonates(III) with Different Sb:S Ratios: Solvothermal Syntheses and Crystal Structures of [(C3H10NO)(C3H10N)][Sb8S13], [(C2H8NO)(C2H8N)(CH5N)][Sb8S13], [(C6H16N2)(C6H14N2)][Sb6S10], and [C8H22N2][Sb4S7]

Four new thioantimonates(III) with compositions [(C₃H₁₀NO)(C₃H₁₀N)][Sb₈S₁₃] ( 1 ) (C₃H₉NO = 1‐amino‐3‐propanol, C₃H₉N = propylamine), [(C₂H₈NO)(C₂H₈N)(CH₅N)][Sb₈S₁₃] ( 2 ) (C₂H₇NO = ethanolamine, C₂H₇N = ethylamine, CH₅N = methylamine), [(C₆H₁₆N₂)(C₆H₁₄N₂)][Sb₆S₁₀] ( 3 ) (C₆H₁₄N₂ = 1,2‐diaminocyclohexane) and [C₈H₂₂N₂][Sb₄S₇] ( 4 ) (C₈H₂₀N₂ = 1,8‐diaminooctane) were synthesized under solvothermal conditions. Compound 1 : triclinic space group P$\bar{1}$ , a = 6.9695(6) Å, b = 13.8095(12) Å, c = 18.0354(17) Å, α = 98.367(11), β = 96.097(11) and γ = 101.281(11)°; compound 2 : monoclinic space group P2₁/m, a = 7.1668(5), b = 25.8986(14), c = 16.0436(11) Å, β = 96.847(8)°; compound 3 : monoclinic space group P2₁/n, a = 11.6194(9), b = 10.2445(5) Å, c = 27.3590(18) Å, β = 91.909(6)°; compound 4 : triclinic space group P$\bar{1}$ , a = 7.0743(6), b = 12.0846(11), c = 13.9933(14) Å, α = 114.723(10), β = 97.595(11), γ = 93.272(11)°. The main structural feature of the two atoms thick layered [Sb₈S₁₃]^2– anion in 1 are large nearly rectangular pores with dimensions 11.2 × 11.7 Å. The layers are stacked perpendicular to [100] to form tunnels being directed along [100]. In contrast to 1 the structure of 2 contains a [Sb₈S₁₃]^2– chain anion with Sb₁₂S₁₂ pores measuring about 8.9 × 11.5 Å. Only if longer Sb–S distances are considered as bonding interactions a layered anion is formed. The chain anion [Sb₆S₁₀]^2– in compound 3 is unique and is constructed by corner‐sharing SbS₃ pyramids. Two symmetry‐related single chains consisting of alternating SbS₃ units and Sb₃S₃ rings are bound to Sb₄S₄ rings in chair conformation. Finally, in the structure of 4 the SbS₃ and SbS₄ moieties are joined corner‐linked to form a chain of alternating SbS₄ units and (SbS₃)₃ blocks. Neighboring chains are connected into sheets that contain relatively large Sb₁₀S₁₀ heterorings. The sheets are further connected by sulfur atoms generating four atoms thick double sheets.

Four New Thioantimonates(III) with the General Formula [TM(tren)]Sb4S7 (TM = Mn,Fe, Co,Zn) with the Transition Metal as Part of a Thioantimonate(III) Network Synthesized under Solvothermal Conditions and Tuning of the Optical Band Gap by the Transition Metal Cation

Four new thioantimonate(III) compounds with the general formula [TM(tren)]Sb₄S₇, TM = Mn 1 , Fe 2 , Co 3 and Zn 4 , were synthesized under solvothermal conditions by reacting elemental TM, Sb and S in an aqueous solution of tren (tren = tris(2‐aminoethyl)amine). All compounds crystallize in the monoclinic space group P2₁/n with four formula units in the unit cell. Single crystal X‐ray analyses of 1 [a = 8.008(2), b = 10.626(2), c = 25.991(5) Å, β = 90.71(3)°, V = 2211.4(8) ų], 2 [a = 8.0030(2), b = 10.5619(2), c = 25.955(5) Å, β = 90.809(3)°, V = 2193.69(8) ų], 3 [a = 7.962(2), b = 10.541(2), c = 25.897(5) Å, β = 90.90(3)°, V = 2173.0(8) ų] and 4 [a = 7.978(2), b = 10.625(2), c = 25.901(5) Å, β = 90.75(3)°, V = 2195.2(8) ų] reveal that the compounds are isostructural. The [Sb₄S₇]^2‐ anions are composed of three SbS₃ trigonal pyramids and one SbS₄ unit as primary building units (PBU). The PBUs share common edges and corners to form semicubes (Sb₃S₄) which may be regarded as secondary building units (SBU). The SBUs and SbS₃ pyramids are joined in an alternating fashion yielding the equation/tex2gif-stack-1.gif[Sb₄S₇^‐] anionic chain which is directed along [100]. Weaker Sb‐S bonding interactions between neighbored chains lead to the formation of layers within the (001) plane which contain pockets that are occupied by the cations. The TM²⁺ ions are in a trigonal bipyramidal environment of four N atoms of the tren ligand and one S atom of the thioantimonate(III) anion. The optical band gaps depend on the TM²⁺ ion and amount to 3.11 eV for 1 , 2.04 eV for 2 , 2.45 eV for 3 , and 2.60 eV for 4 .

Another Example for the Ability of the $\rm SbS^{3-}_{3}$ Anion to act as a Bidentate Ligand: Solvothermal Synthesis,Crystal Structure,Calculated and Experimental Raman Spectra of [Cr(tren)SbS3]·H2O

The new charge neutral complex [Cr(tren)SbS₃]·H₂O was synthesized under solvothermal conditions applying CrCl₃·6H₂O, Sb₂S₃, and S as starting material in an aqueous tren solution (tren = tris(2‐aminoethyl)amine)). The compound crystallizes in the non‐centrosymmetric space group P2₁2₁2₁ with a = 8.7779(15), b = 10.7122(17), c = 15.4286(18) Å, V = 1450.8(4) ų. In the structure the Cr³⁺ ion is surrounded by four N atoms of the amine molecules and by two S atoms of a trigonal pyramidal [SbS₃]^3? group, i.e., the latter acts as a bidentate ligand. A three‐dimensional network is formed via hydrogen bonds between the complexes and water molecules. The main resonances in the Raman spectrum can be explained on the basis of calculated data. The most intense band is due to the Sb‐S stretching vibration. The thermal properties were investigated by DTA‐TG measurements. On heating [Cr(tren)SbS₃]·H₂O decomposes in two distinct steps. The first step corresponds to the removal of the water molecules and the second step to the loss of the tren ligand.     

Solvothermal Synthesis and Crystal Structure of a Layered Thioantimonate(Ⅲ) [C_4H_9NH_3]_2Sb_4S_7

An inorganic-organic hybrid thioantimonate(Ⅲ) [CH3(CH2)3NH3]2Sb4S7 1 with layered structure was synthesized by solvothermal method. 1 crystallizes in the triclinic system,space group P1 with a=7.0124(11),b=11.919(2),c=14.879(3),α=108.791(3),β=102.441(3),γ=92.846(2)o,V=1140.1(3)3,Mr=859.71,Z=2,Dc=2.504 g/cm3,μ =5.324 mm-1,F(000)=804,S=1.013,the final R=0.0297 and wR=0.0618 for 3534 observed reflections with I > 2σ(I). 1 consists of [C4H9NH3]+ cations and two-dimensional [Sb4S7]n2n- anion which is composed of three SbS3 trigonal pyramids and one SbS4 unit joined by sharing common corners. The anionic layers are stacked perpendicularly to the c axis of the unit cell forming two-dimensional channels between the layers. The [C4H9NH3]+ cations interdigitate in a bilayer and reside in the 2D channels leading to a sandwich-like arrangement of the anion and cations.
