Binary complex salts [Ru(NH3)5Cl][ReCl6] and [Ru(NH3)5Cl]2[ReCl6]Cl2 were synthesized and characterized. An X-ray diffraction analysis showed that they were isostructural with the previously
obtained isoformula salts [Rh(NH3)5Cl][OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2, respectively. Thermolysis of these compounds under hydrogen and helium was studied. According to X-ray phase analysis data,
bimetallic solid solutions Ru0.67Re0.33 and Ru0.50Re0.50 were the final products of thermolysis. Their unit cell parameters correspond to the characteristics of alloys with similar
compositions.

The thermolysis of the complexes [Co(NH3)6]2C2O4[Cu(C2O4)2]2 (I) and [Co(NH3)6]Cl[Cu(C7H4O3)2] (II) in air and hydrogen at 200, 350, and 500°C and the composition and properties of the thermolysis products are considered.
The oxidative thermolysis of the complexes yields mixtures of cobalt and copper oxides, including mixed ones. The reductive
thermolysis of the complexes yields a Co + Cu bimetallic powder in the case of compound I and a Co + Cu + C powder in the
case of compound II. The thermal behavior of the complexes is governed by the nature of the ligand coordinated to the copper
atom. The observed data are explicable in terms of the properties of this ligand. The chemistry of the oxidative and reductive
thermolysis is discussed.

Double complexes [Pt(NH3)5Cl][Fe(C2O4)3] · 4H2O, [Pt(NH3)5Cl][Co(C2O4)3] · 2H2O, and [Pt(NH3)5Cl][Cr(C2O4)3] · 4H2O were synthesized and studied by single-crystal X-ray diffraction, X-ray phase analysis, differential thermal analysis, elemental
analysis, and IR spectroscopy. The crystal structures of the compounds were examined from the viewpoint of the close packing
of coordination polyhedra. The thermal properties of the synthesized complexes and K3[M(C2O4)3] salts (M = Fe, Co, Cr) were compared. A procedure for the synthesis of the FePt, CoPt, and CrPt intermetallic compounds
through the thermolysis of the obtained complexes was developed.

The double complex salts [Ir(NH3)5Cl][IrCl6], [Ru(NH3)5Cl][IrCl6], and [Ru(NH3)5Cl]2[IrCl6]Cl2 have been synthesized and characterized. An X-ray diffraction study demonstrated that these salts are isostructural with [Rh(NH3)5Cl][OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2 synthesized earlier. Thermolysis of these salts in hydrogen and helium has been studied. X-ray powder diffraction analysis show that thermolysis yields stoichiometric solid solutions of metals as the final products. The unit cell parameters of these products correspond to equilibrium phases. 相似文献

A general motif of the crystal structure of [Rh(NH3)5Cl]2[Re6S8(CN)6]·3H2O is examined, and the cluster anions are found to form a pseudo-hexagonal sublattice. The thermal decomposition of [Rh(NH3)5Cl]2[Re6S8(CN)6]·3H2O is studied, and it is shown that in helium atmosphere thermolysis occurs through the formation of intermediate amorphous
phases. The final product obtained at 1200°C is a disordered single-phase solid solution of Re0.75Rh0.25 based on the structure of rhenium. Powder X-ray diffraction data for solid solutions in the system of Rh-Re are surveyed.
It is demonstrated that the data for phases prepared by the thermal decomposition of coordination compounds better match the
theoretical state diagram than the experimental one. The dependence of atomic volume on the composition of solid solutions
of RexRh1−x
is derived.

The thermolysis of complexes [Co(NH3)6][Fe(CN)6] and [Co(NH3
6]4[Fe(CN)6]3 under an air or hydrogen atmosphere at 200, 350, and 500°C is studied. The composition and properties of thermolysis products
are determined. The oxidative thermolysis yields mixtures of oxides of the central metals; the reductive thermolysis yields
intermetallic compounds CoFe. The density of the complexes and the specific surface area of the intermetallic compounds are
measured. Average particle sizes are calculated. The morphology and dispersion of the powders are dictated by the shape and
density of the crystals of the precursor double salts and the thermolysis temperature. The thermolysis chemism in the oxidative
and reductive atmospheres is discussed in the context of the nature of the complex anion.

A re-interpretation and re-evaluation of single-crystal X-ray diffraction data of a previously reported ‘(NH4)2(NH3)[Ni(NH3)2Cl4]’ (J. Solid State Chem. 162 (2001) 254) give a new formula (NH4)2−2z[Ni(NH3)2]z[Ni(NH3)2Cl4] with z=0.152. This new formula results from defects in an idealized ‘(NH4)2[Ni(NH3)2Cl4]’ basic structure, where two adjacent NH4+ cations are replaced by one Ni(NH3)22+ unit. Cl− anions from the basic structure complete the coordination sphere of the new Ni2+ to [Ni(NH3)2Cl4]2−. 相似文献

Preparation and Crystal Structure of (NH4)2[V(NH3)Cl5]. The Crystal Chemistry of the Compounds (NH4)2[V(NH3)Cl5], [Rh(NH3)5Cl]Cl2, and M2VXCl5 with M = K, NH4, Rb, Cs and X ? Cl, O (NH4)2[V(NH3)Cl5] crystallizes like [Rh(NH3)5Cl]Cl2 in the orthorhombic space group Pnma with Z = 4. The compounds are built up by isolated NH4+ or Cl? and complex MX5Y ions. The following distances have been observed: V? N: 213.8, V? Cl: 235.8–239.1, Rh? N: 207.1–208.5, Rh? Cl: 235.5 pm. Both structures differ from the K2PtCl6 type mainly in the ordering of the MX5Y polyhedra. The compounds M2VCl6 and M2VOCl5 with M = K, NH4, Rb, and Cs crystallize with exception of the orthorhombic K2VOCl5 in the K2PtCl6 type. The ordering of the MX5Y polyhedra in the compounds (NH4)2[V(NH3)Cl5], [Rh(NH3)5Cl]Cl2 and K2VOCl5 enables a closer packing. 相似文献

The Structures of some Hexaammine Metal(II) Halides of 3 d Metals: [V(NH3)6]I2, [Cr(NH3)6]I2, [Mn(NH3)6]Cl2, [Fe(NH3)6]Cl2, [Fe(NH3)6]Br2, [Co(NH3)6]Br2 and [Ni(NH3)6]Cl2 Crystals of yellow [V(NH3)6]I2 and green [Cr(NH3)6]I2 were obtained by the reaction of VI2 and CrI2 with liquid ammonia at room temperature. Colourless crystals of [Mn(NH3)6]Cl2 were obtained from Mn and NH4Cl in supercritical ammonia. Colourless transparent crystals of [Fe(NH3)6]Cl2 and [Fe(NH3)6]Br2 were obtained by the reaction of FeCl2 and FeBr2 with supercritical ammonia at 400°C. Under the same conditions orange crystals of [Co(NH3)6]Br2 were obtained from [Co2(NH2)3(NH3)6]Br3. Purple crystals of [Ni(NH3)6]Cl2 were obtained by the reaction of NiCl2 · 6H2O and NH4Cl with aqueous NH3 solution. The structures of the isotypic compounds (Fm3 m, Z = 4) were determined from single crystal diffractometer data (see “Inhaltsübersicht”). All compounds crystallize in the K2[PtCl6] structure type. In these compounds the metal ions have high-spin configuration. The orientation of the dynamically disordered hydrogen atoms of the ammonia ligands is discussed. 相似文献

Double complex salts (DCSs) [Co(NH3)6][Fe(CN)6] (I) and [Co(NH3)6]2[Cu(C2O4)2]3 (II) and complex [Co(NH3)6]2(C2O4)3·4H2O (III) are synthesized and investigated by single crystal XRD, crystal optics, and elemental analysis. The crystalline phases of
I, II, and III (R-3, P21/c, and Pnnm space groups respectively) have the following crystallographic characteristics: a = 10.9804(2) ?, b = 10.9804(2) ?, c = 10.8224(3) ?, V = 1130.03(4) ?3, Z = 3, d

x = 1.68 g/cm3 (III). This paper investigates the products of DCS thermolysis in a hydrogen atmosphere: the intermetallic compound CoFe with
the bcc parameter a = 2.852 ? for I and a heterogeneous mixture of Co and Cu in the decomposition of II. The coordinated CN− and C2O42− groups then turn into NH3, hydrocarbons, and CO2. The dominant hydrocarbon is methane. 相似文献

The unit cell parameters of the resulting salts were refined. The metal powders, which were obtained by thermal decomposition of these salts under an atmosphere of hydrogen, were studied by powder X-ray analysis. 相似文献

The small di- and triatomic molecules [SN]+ and [SNS]+ have shown versatile chemistries and [SNS]+ is an important starting reagent for many sulfur-nitrogen radicals. However, their chemistry is limited to the more polar solvents (e.g. SO2). In this work an attempt is made to increase their solubility in less polar solvents by exchange of the usual [MF6]− (M = As, Sb) anions by the large and weakly coordinating [Al(OC(CF3)3)4]−. As expected the metathesis reactions of [SN][AsF6] and [SNS][SbF6] with Li[Al(OC(CF3)3)4] in liquid sulfur dioxide resulted in the formation of the insoluble Li[SbF6], which is the driving force for these metathesis reactions. The characterization of the compounds by IR and multinuclear NMR revealed that [SNS]+ formed a [Al(OC(CF3)3)4]− salt in a clean reaction. A preliminary crystal structure of [SNS][Al(OC(CF3)3)4] is presented. The solubility of [SNS][Al(OC(CF3)3)4] in CH2Cl2 is significantly increased with respect to the corresponding [MF6]− salts, and potentially opens up new areas of [SNS]+ chemistry. The reaction of the more reactive [SN]+ with Li[Al(OC(CF3)3)4] was less clear. Multinuclear NMR and IR spectra were consistent with the formation of [SN][Al(OC(CF3)3)4], which also showed significant decomposition. 相似文献

The di-nitrile complexes trans-[PtCl2(NCR)2] (R = Me, Ph, CH2Ph) react with an excess of gaseous NH3 in CH2Cl2 at −10 °C to form, in high yield, the corresponding di-amidine complexes trans-[PtCl(NH3){HNC(NH2)R}2]Cl in which also one chlorine ligand has been displaced by NH3. The 1H NMR spectra in DMSO showed the formation of different species which were characterized through NOESY, TOCSY and 1H/13C heteronuclear correlations as trans-[Pt(NH3){HNC(NH2)R}2(DMSO)]Cl2 and trans-[PtCl{HNC(NH2)R}2(DMSO)]Cl. 相似文献

Double complex salts [Ru(NH3)5Cl][OsCl6] and [Ru(NH3)5Cl]2[OsCl6]Cl2 were prepared and characterized. An X-ray diffraction study showed that [Ru(NH3)5Cl][OsCl6] is isostructural to the previously synthesized [Rh(NH3)5Cl][OsCl6]. The structure of [Ru(NH3)5Cl]2[OsCl6]Cl2 was solved by X-ray diffraction (a = 11.1849(8) ?, b = 7.9528(6) ?, c = 13.4122(9) ?; β = 99.765(2)°; V= 1175.75 ?3; space group C2/m; Z = 2). Thermolysis of the compounds under hydrogen and helium was studied. According to X-ray diffraction, nanosized metallic
powders of the corresponding alloys are formed as the final products of thermolysis. The compositions of the obtained solid
solutions are consistent with the phase diagram of the Ru-Os system. 相似文献

TeX4 (X = Cl, Br) react in HCl/HBr with [Ph(CH3)2Te]X (X = Cl, Br) to give [PhTe(CH3)2]2[TeCl6] (1) and [PhTe(CH3)2]2[TeBr6] (2). The reaction of PhTeX3 (X = Cl, Br, I) in cooled methanol with [(Ph)3Te]X (X = Cl, Br, I) leads to [Ph3Te][PhTeCl4] (3), [Ph3Te][PhTeBr4] (4) and [Ph3Te][PhTeI4] (5). In the lattices of the telluronium tellurolate salts 1 and 2, octahedral TeCl6 and TeBr6 dianions are linked by telluronium cations through Te?Cl and Te?Br secondary bonds, attaining bidimensional (1) and three-dimensional (2) assemblies. The complexes 3, 4 and 5 show two kinds of Te?halogen secondary interactions: the anion-anion interactions, which form centrosymmetric dimers, and two identical sets of three telluronium-tellurolate interactions, which accomplish the centrosymmetric fundamental moiety of the supramolecular arrays of the three compounds, with the tellurium atoms attaining distorted octahedral geometries. Also phenyl C-H?halogen secondary interactions are structure forming forces in the crystalline structures of compounds 3, 4 and 5. 相似文献

Single crystals of diammonium tetranitratouranylate (NH4)2[UO2(NO3)4] (I) and a new diammonium tetranitratouranylate complex with 18-crown-6 [(NH4)(18C6)]2[UO2(NO3)4] (II) have been synthesized by the reaction of diaquadinitratouranyl tetrahydrate with ammonium nitrate in a nitric acid solution
and the reaction of the same reagents with 18C6 in an ethanol solution, respectively. The X-ray diffraction analysis of compounds
I and II has been performed. Crystals of compounds I and II are monoclinic, Z = 2, space group P21/n, a = 6.4075(5) ?, b = 7.7851(7) ?, c = 12.4461(12) ?, β = 101.239(1)°, V = 608. 94(9) ?3 for compound I and a = 10.542(9) ?, b = 8.590(8) ?, c = 22.5019(19) ?, β = 101.632(1)°, V = 2058.3(3) ?3 for compound II. The [UO2(NO3)4]2− complex anion in compounds I and II contains two monodentate and two bidentate cyclic nitrato groups, and the coordination number of uranyl is 6. The 18C6 molecule
in the structure of compound II has the classic crown conformation and combined with the ammonium ion by three hydrogen bonds. Compounds I and II formed by electrostatic attraction forces between counterions are stabilized by (NH4+)NH...O(NO3−) interionic hydrogen bonds. 相似文献

With several chloro ruthenium phosphine complexes, allyldifluorophosphite, F2POC3H5, displaces triphenylphosphine to form new compounds in which it acts as a phosphorus donor ligand. The new complexes [PPh3]2[F2POC3H5]Ru[CO][Cl][H], I, and [(PPh3)2(F2POC3H5)2RuCl2]nII, hav characterized by chemical, spectroscopic, and, in the case of I, crystallographic means. This behaviour of F2POC3H5 contrasts to its reactions with several platinum and palladium chloro complexes where it undergoes Arbuzov-type rearrangements. 相似文献
