The thermal decomposition of two complex inorganic azides, i.e. Cs2Zn(N3)4 and K2Zn(N3)4, has been studied. Decomposition proceeds from the melt in the temperature range from 285–330°C and 310–360°C, resp., the main reaction products being N2 and small solid particles of Zn3N2 containing minor amounts of finely divided metallic zinc. The alkali metal component (CsN3 and KN3) is stable to decomposition in the temperature region investigated. The kinetics of the decomposition process are described in terms of the acceleratory action of the solid Zn3N2(Zn)-particles and their mutual agglomeration with increasing fractional decompositionX (kinetic models I and III). In the final stages of decomposition the metal azide component may crystallize from the melt. This situation is accounted for within the kinetic model IV. The experimental data [X(t)-isotherms] have been analyzed with respect to the postulated kinetic models by statistical techniques (nonlinear regression).

Phase diagram of the binary system AgNO3—RbNO3 was studied using thermal analysis technique, differential scanning calorimetry and X-ray diffraction. This binary exhibits a congruently melting compound Ag0.5Rb0.5NO3 (m. p.=138°C), an incongruently melting one Ag0.33Rb0.66NO3 with two polymorphic varieties, two eutectics at (36 mol% RbNO3, 128°C) and at (60 mol% RbNO3, near 134°C) respectively and a peritectic at (60.5 mol% RbNO3, 141°C). This system contains also three invariant reactions at 164, 222 and 282°C due to the phase transitions of RbNO3 and another one at 164°C due to the phase transition of AgNO3.

The vaporization chemistry of In2Te3(s) was studied by the computer-automated simultaneousKnudsen-effusion and torsion-effusion method, by high-temperature mass spectrometry, and by ancillary methods. The first absolute measurements of the vapor pressure of In2Te3 are reported. In2Te3(s) vaporized incongruently in the temperature range 701–889 K and produced Te2(g) and a solid-solution, (X In=0.42 andX Te=0.58). The standard enthalpy of the reaction at 298 K, H° (298 K) by the third-law method was 136.0±0.3 kJ/mol of vapor. The above solid solution vaporized incongruently and produced InTe(s) and a vapor which consisted of Te2(g) and In2Te(g). InTe(s) vaporized congruently in the range 701–887 K and produced Te2(g) and In2Te(g); the third-law H v ° (298 K) was 201.5±1.0 kJ/mol. These results were at variance with the literature on vaporization of In2Te3 where both congruent vaporization and incongruent vaporization to give InTe(s) are separately reported. Further, InTe(s) was reported to vaporize incongruently. These differences are discussed.Dedicated to Professor Dr.Kurt L. Komarek on the occasion of his 60th birthday.  相似文献

Zusammenfassung Das Verhalten von Diphenylacetylen, Phenylacetylen und 1-Phenyl-2-trimethylsilylacetylen gegenüber dem System Pb(OAc)4–(CH3)3SiN3 bei –20° läßt sich so interpretieren, als ob positives Azid transferiert würde. Bei Raumtemp. kann auch ein radikalischer Reaktionsablauf in Erwägung gezogen werden.
Transfer reactions with Pb(OAc)4–n(N3)n (the reactivity of triple bonds, VII)
The behaviour of diphenylacetylene, phenylacetylene and 1-phenyl-2-trimethylsilylacetylene against the mixture Pb(OAc)4–(CH3)3SiN3 can be interpreted at –20°C, by a transfer of formally positive azide. At room-temperature a radical mechanismus can be involved too.

A phase diagram of the [Zn(MePy)2(NCS)2]-MePy binary system has been studied by DTA and solubility methods. Two compounds melting incongruently (at 63 and 57°C) have been discovered in the system. They have been obtained as separate phases with crystals of different shape (needles and octahedra). Their composition has been determined by analytical methods and verified by X-ray structural analysis: [Zn(MePy)4(NCS)2]·0.67 MePy·xH2O, wherex depends on the synthesis conditions, and [Zn(MePy)4(NCS)2]·MePy, respectively.The preliminary X-ray study of the first compound (at –100°C) has shown it to be isostructural with the known clathrates of the common formula [M(MePy)4(NCS)2]·0.67MePy·xH2O, where M=Cu, Mn, Mg andx=0–0.33. The unit cell parameters are as follows:a=27.20(1),c=11.202(4) Å, space group ,Z=9.The X-ray study of [Zn(MePy)4(NCS)2]·MePy (at–50°C) has shown it to be analogous to the organic zeolite -phase with the guest MePy molecules located in the channels formed by molecular packing of the [Zn(MePy)4(NCS)2]host. The cell is tetragonal, the space groupI41/a,a=16.845(6),c=23.496(7) Å,V=6667(4) Å3,Z=8,D calc=1.289 g cm–3,R=0.074. The zinc cation is surrounded by a slightly irregular octahedron of six nitrogen atoms of the MePy and NCS ligands. The crystallisation field of the host [Zn(MePy)4(NCS)2] complex in the temperature range concerned is absent in the phase diagram. It suggests contact stabilization of the [Zn(MePy)4(NCS)2] molecule by the guest in the clathrates.

Preparation and Crystal Structure of Diammin Magnesium Diazide Mg(NH3)2(N3)2 Diammin magnesium diazide was synthesized from Mg3N2 and NH4N3 in liquid ammonia and crystallized at 150 °C under autogenous atmosphere of HN3 and NH3 using sealed ampoules. Mg(NH3)2(N3)2 is a colorless, microcrystalline powder which can detonate above 180 °C. Caution, preparation and manipulation of Mg(NH3)2(N3)2 is very dangerous! The crystal structure was solved from powder data using the Patterson method and a Rietveld refinement was performed (Mg(NH3)2(N3)2, I 4/m, no. 87; a = 6.3519(1), c = 7.9176(2) Å; Z = 2, R(F2)= 0.1162). The crystal structure of Mg(NH3)2(N3)2 is related to that of SnF4. It consists of planes built up from corner sharing Mg(NH3)2(N3)4 octahedra connected equatorially over their four azide bridges with the ammonia ligands being in trans position. IR data were collected and interpreted in accordance with the structural data.  相似文献

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.  相似文献

A thorough study of compounds with the formula W2Cl4(NHCMe3)2(PR3)2, withR 3=Me3, Et3, Prg n 3 Me2,Ph, is reported. In addition to the previously reported crystalline compounds, namely Ia,trans-W2Cl4(NHCMe3)2(PMe3)2 in space group Pmmn;3a,trans-W2Cl4(NHCM3)2(PEt3)2 in space group P21/a (or P21/c); and4,cis-W2Cl4(NHCMe3)2(PMe2Ph)2 in Pna21, we have obtained and structurally characterized the following new substances,1b,trans-W2Cl4,(NHCMe3)2(PMe2)2, space group P21/c,a= 12.233 (4) Å,b= 12.872 (4) Å,c=17.095 (5) Å,=93.52 (2)°,Z=4,V=2687 (1) Å3 2,cis-W2Cl4(NHCMe3)2(PMe3)2, P21/c,a=9.673 (4) Å,b=17.249 (4) Å,c=16.244 (5) Å,=99.63 (3),Z = 4 ,V=2669 (1) Å.3b,trans-W2Cl4(NHCMe3)2(PEt3)2, Pl,a=16.850 (3) Å,b=17.797 (3) Å,c= 11.459 (2)Å,= 101.02 (1),= 103.13°, y=84.23 (1)°,Z=4,V= 3279 (1) Å5,trans-W2Cl4(NHCM3)2(PMe2Ph)2, Fdd2,a=39.563 (8) Å at 20°C; 39.325 (10) Å at -6O°C,b = 57.543 (17) Å at 20°C; 57.186 (16) Å at -60°C,c= 8.810 (1) Å at 20°C; 8.770 (1) Å at - 60°C ,Z=24,V=20057 (7) Å3 (20°C), 19723 (8) Å3 ( - 60°C) .6,trans-W2Cl4(NHCMe3 2(PPrn 3)2, Pl,a= 17.287 (2) Å (20°C); 17.077 (5) Å (-60°C),b= 19.119 (2) Å (20°C); 18.952 (6) Å (-60°C),c= 12.713 (1) Å (20°C); 12.668 (4) Å (-60°C),Z=4,V= 3980 (1) Å3 (20°C), 3898 (2) ,Å3 ( - 60°C). In addition, the structure of3a was re-determined and refined so that the disorder ratio was a refined parameter, leading to a value of 0.520:0.480 instead of being arbitrarily fixed at 0.50:0.50. In all of the structures the molecules are held in eclipsed (but very distorted) rotational conformations and the W-W distances are all within the range of 2.305-2.330 Å. As will be shown in a later paper, for all phosphines, thecis andtrans isomers are of similar stability and an equilibrium mixture exists in solution. It is also shown that1a and3a do not contain unexpectedly short W-N bonds as previously reported.  相似文献

Tetrameric [{RZn(NHNMe2)}4] (R = Me, Et), the first organometallic zinc hydrazides to be described, have been prepared by alkane elimination from dialkylzinc solutions and N,N‐dimethylhydrazine. They were characterised by 1H and 13C NMR and IR spectroscopy, mass spectrometry, elemental analysis and X‐ray crystallography. The compounds form asymmetric aggregates containing the novel Zn4N8 core; tetrahedra of Zn atoms bear the alkyl groups at Zn, with the triangular faces bridged by NHNMe2 substituents. The NH groups are connected to two Zn atoms, and the NMe2 groups to one. Hydrolysis of the compounds with water gives [(RZn)4(OH)(NHNMe2)3] as products, which also were characterised as described above. Higher yields of these hydroxo clusters were achieved in one‐pot syntheses by reaction of dialkylzinc solutions with mixtures of N,N‐dimethylhydrazine and water. They contain Zn4N6O cages, in which one hydroxide in the tetrameric hydrazides described above replaces one NHNMe2 group. Similar products can be prepared with alkoxy instead of hydroxy groups, in analogous one‐pot syntheses with alcohols. Alcoholysis of [EtZn(NHNMe2)]4 with methanol or ethanol gave zinc trishydrazide monoalkoxides, [(EtZn)4(OR)(NHNMe2)3] (R = Me, Et), which have constitutions analogous to the monohydroxides. The organozinc bishydrazide bisalkoxides [(MeZn)4(NHNMe2)2(OEt)2] and [(EtZn)4(NHNMe2)2(OEt)2] were obtained in one‐pot reactions from dialkylzinc solutions with mixtures of the hydrazine and alcohol, and their crystal structures, confirmed by spectroscopic methods in solution, show an unsymmetrical aggregation with the novel Zn4N4O2 cage structure.  相似文献

In mononuclear [Zn(C10H9N3)2(N3)2]·H2O, the zinc atom has an approximate octahedral geometry, coordinated with four pyridyl nitrogen atoms derived from two bis(2‐pyridyl)amine molecules and two terminal nitrogen donors of the azide anions. Hydrogen‐bonding interactions extend this structure to form a double‐layer architecture. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

Two new isotypic triple molybdates, namely tri­cesium lithium dicobalt tetra­kis­(tetra­oxo­molybdate), Cs3LiCo2(MoO4)4, and tri­rubidium lithium dizinc tetra­kis­(tetra­oxo­molybdate), Rb3LiZn2(MoO4)4, crystallize in the non‐centrosymmetric cubic space group I3d and adopt the Cs6Zn5(MoO4)8 structure type. In the parent structure, the Zn positions have 5/6 occupancy, while they are fully occupied by statistically distributed M2+ and Li+ cations in the title compounds. In both structures, all corners of the (M2/3Li1/3)O4 tetra­hedra (M = Co and Zn), having point symmetry , are shared with the MoO4 tetra­hedra, which lie on threefold axes and share corners with three (M,Li)O4 tetra­hedra to form open mixed frameworks. Large alkaline cations occupy distorted cubocta­hedral cavities with symmetry. The mixed tetra­hedral frameworks in the structures are close to those of mayenite (12CaO·7Al2O3) and the related compounds 11CaO·7Al2O3·CaF2, wadalite (Ca6Al5Si2O16Cl3) and Na6Zn3(AsO4)4·3H2O, but the terminal vertices of the MoO4 tetra­hedra are directed in opposite directions along the threefold axes compared with the configurations of Al(Si)O4 or AsO4 tetra­hedra. The cation arrangements in Cs3LiCo2(MoO4)4, Rb3LiZn2(MoO4)4 and Cs6Zn5(MoO4)8 repeat the structure of Y3Au3Sb4, being stuffed derivatives of the Th3P4 type.  相似文献

Zusammenfassung Beim thermischen Zerfall von Ba(N3)2-Einkristallen gehen unabhängig von den experimentellen Bedingungen (Einwaage, Temperatur, Gasatmosphäre) stets 70 bis 73% (bei Pulvern 75%) des Azides in Bariumnitrid, Ba3N2, über, der Rest in metall. Barium. Die Nitridbildung wird durch Messung der Zerfallswärme (DDK-Methode), aus der Druckbilanz, analytisch und röntgenographisch bewiesen. Die Nitridbildung setzt unmittelbar mit Zersetzungsbeginn ein und die Nitridmenge liegt bei kleinen Umsätzen sogar über dem konstanten Endwert. Bei den vorliegenden exper. Bedingungen (Temperaturen unter 150° C) findet keine Sekundärreaktion von primär gebildetem Ba mit N2 im elektronischen Grundzustand statt, sondern die Nitridbildung erfolgt an der Zerfallsgrenzfläche unmittelbar im Anschluß an den eigentlichen Zersetzungsvorgang. Das konstante Verhältnis von Ba3N2 Ba wird durch Annahme der instabilen Zwischenverbindung Ba2N2, die im gefundenen Verhältnis in Ba und Ba3N2 weiterzerfällt, erklärt. Die Verbindung Ba2N2 entsteht durch Reaktion von elektronisch angeregtem N2 * (aus der Rekombinationsreaktion zweier Azidradikale N3 0) mit Ba2-Aggregaten an der Zerfallsgrenzfläche. Letztere Reaktion erklärt gleichzeitig das Nichtauftreten der vonAudubert beim thermischen Zerfall von Alkali- und Schwermetallaziden gefundenen UV-Strahlung im Fall der Erdalkaliazide.
Independent of the experimental conditions (temperature, weight-in, gas atmosphere) there are always forming 70 to 73 percent of bariumnitride, Ba3N2, during thermal decomposition of Ba(N3)2 single crystals (in the case of ground material 75 percent) the rest transforms into metallic barium. Nitride formation has been proved from the pressure balance, analytically, by X-ray studies and by measuring the heat of reaction (DDK-method). Nitride formation starts immediately at the beginning of the decomposition and the amount of nitride in this stage even exceeds the constant final value. Within the experimental conditions of decomposition (temperatures below 150° C) no secondary reaction occurs between N2 in its electronic ground state (present in the apparatus) and metallic barium to nitride and therefore nitride formation must be connected immediately to the decomposition process. The constant ratio of Ba3N2 to Ba (31) can be explained by suggesting an instable intermediary compound Ba2N2 which decomposes into Ba and Ba3N2 in the ratio given above. Ba2N2 forms at the interface by a reaction between activated N2 * (arising from the recombination of two N3 0 radicals) and Ba2-aggregates. Deactivation of activated N2 * by the above reaction explains that the UV radiation found byAudubert during the thermal decomposition of alkaline- and heavy metal azides is only very weak in the case of alkaline earth azides.

The transparent dark orange compounds Cs2[Pd(N3)4] and Rb2[Pd(N3)4]·2/3H2O are synthesized by reaction of the respective binary alkali metal azides with K2PdCl4 in aqueous solutions. According to single‐crystal X‐ray diffraction investigations, the novel ternary azidopalladates(II) crystallize in the monoclinic space group P21/c (no. 14) with a = 705.7(2) pm, b = 717.3(2) pm, c = 1125.2(5) pm, β = 104.58(2)°, mP30 for Cs2[Pd(N3)4] and a = 1041.4(1) pm, b = 1292.9(2) pm, c = 1198.7(1) pm, β = 91.93(1)°, mP102 for Rb2[Pd(N3)4]·2/3H2O, respectively. Predominant structural features of both compounds are discrete [PdII(N3)4]2– anions with palladium in a planar coordination by nitrogen, but differing in point group symmetries., The vibrational spectra of the compounds are analyzed based on the idealized point group C4h of the spectroscopically relevant unit, [Pd(N3)4]2– taking into account the site symmetry splitting due to the symmetry reduction in the solid phase.  相似文献

Reaction of the N-(2-pyridyl)carbonylaniline ligand (L) with Cu(NO3)2, Cu(ClO4)2, Zn(ClO4)2, Ni(NO3)2 and PdCl2 gives complexes with stoichiometry [Cu(L)2(H2O)2](NO3)2, [Cu(L)2(H2O)2](ClO4)2, [Zn(L)2(H2O)2] (ClO4)2, [Ni(L)2(H2O)Cl](NO3) and PdLCl2. The new complexes were characterized by elemental analyses and infrared spectra. The crystal structures of [Cu(L)2(H2O)2](NO3)2, [Cu(L)2(H2O)2](ClO4)2, and [Zn(L)2(H2O)2](ClO4)2 were determined by X-ray crystallography. The cation complexes [M(L)2(H2O)2] contain copper(II) and zinc(II) with distorted octahedral geometry with two N-(2-pyridyl)carbonylaniline (L) ligands occupying the equatorial sites. The hexa-coordinated metal atoms are bonded to two pyridinic nitrogens, two carbonyl oxygens and two water molecules occupying the axial sites. Both the coordinated water molecules and uncoordinated amide NH groups of the N-(2-pyridyl)carbonylaniline (L) ligands are involved in hydrogen bonding, resulting in infinite hydrogen-bonded chains running in one and two-dimensions.  相似文献

Hydrazinium(2+) hexafluoroantimonate was prepared by the reaction of N2H6F2 with an excess of SbF5 in anhydrous HF as solvent. The compound was characterized by chemical analysis and vibrational spectra. The X-ray powder photograph was indexed on the basis of a monoclinic cell witha=8.22(2),b=10.04(3),c=9.51(2) Å,=97.2(2)° andV=780 Å3.The thermal decomposition study of N2H6(SbF6)2 showed that it decomposed to gaseous components through an intermediate, a mixture of N2H5SbF6 and NH4SbF6. In the DSC curve, a strong endothermic effect and medium exothermic and endothermic effects were observed in the range 25–600°C.
