Die Kristallstruktur des Tetracäsium-μ-oxo-decachlorodiosmat(IV), Cs4[Os2O Cl10]

Crystal Structure of Tetracäsium-μ-oxo-decachlordiosmate(IV), Cs₄Os₂OCl₁₀] The anhydrous binuclear complex Cs₄Os₂OCl₁₀] crystallizes with an orthorhombic unit cell, Pcab, a = 12.521, b = 13.994, c = 11.798 Å and Z = 4 formula units. The complex anion forms corner sharing octahedrons tetragonally deformed. The interatomic distances are Os ? O = 1.778 Å and Os ? Cl = 2.370 (4×) and 2.433 Å (1×) respectively. The Cs atoms are coordinated differently. The interatomic distances Cs ? Cl range from 3.46 to 3.87 Å. The structure is discussed in connection with analogous complexes. Details of other polynuclear complexes of Os are added.
