[en] Methods of microstructure analysis, differential thermal analysis, X-ray phase analysis and measurements of the electric conductivity and of the thermoelectric power factor are used to study the Sb₂Tesub(2.9) - SnI₂ system. The system comprises areas of monotectic transformations and a narrow range of solid solutions based on stibium telluride, extending up to 3 mol. %

[en] Several novel organoperoxo complexes of Nb(V), Ta(V) and Sb(V) have been synthesized and characterized. The complexes have the compositions [M(O₂)₂L Cl] and [M(O₂)₂L'] [L = monodentate and bidentate, neutral ligand; L' = bidentate, uninegative ligand]. These complexes are very reactive to both organic and inorganic substrates. Niobium and tantalum complexes were found to oxidize phosphines and arsines to their oxides. These also oxidize olefins to epoxides under stoichiometric conditions while under catalytic conditions, ring opening of the epoxides occur producing α-hydroxyketone when the substrate is trans-stilbene. The antimony complexes are decidedly inert towards oxidation. (author)

[en] The structure of CsSbF⁴ crystal was determined on the basis of diffractometric data: a=9.566(4), b=15.804(6), c=6.360(3) A, d(meas)=4.55, d(calc)=4.57 g/cm₃, μ(MoKsub(α))=131.06 cm^-₁, z=8, f. gr. Pbam. There are two . crystallographically independent antimony atoms with SbEF⁵ octahedrons (Sb-F 1.91-2.29 A) as coordination polyhedrons in the structure. Octahedrons are connected between themselves with common vertexes in chains

[en] The crystal structure of CsSbClF₃ relating to tetragonal syngony has been determined: a=9.94(2), c=11.61(2)A, Z=8, spatial group I anti4 2m. The structure of CsSbClF₃ is built from four-nuclear anionic complexes [Sb₄Cl₄F₁₂]^4- grouped in layers parallel to the xy plane and from cations Cs⁺. The complexes [Sb₄Cl₄F₁₂]^4- are formed from four polyhedrons of antimony connected with one another by the bridge chlorine atoms. Taking into account an unshared s-electron pair of the antimony atom, the coordination polyhedron in the structure of CsSbClF₃ can be described as a deformed octahedron of SbCl₂F₃E with a free electron pair in an axial vertex

[en] Triarylantimony Ar₃Sb (Ar = 4-FC₆H₄, 3-MeC₆H₄) is oxidized by hydrogen peroxide to form tetranuclear complexes [(4-FC₆H₄)₂SbO]₄(O₂)₂ and [(3-MeC₆H₄)₂SbO]₄(O₂)₂ (as a DMSO solvate). The structure of the resulting compounds was examined by single crystal X-ray diffraction analysis.
