Abstract

Alkylosmium(VI) complexes of compositions R₂OsO₂·(L) and R₂OsO₂·(L)₂ are accessible from glycolate osmium(VI) complexes (R = CH₃, CH₂Si(CH₃)₃; L = pyridine). The equilibrium R₂OsO₂·(L)₂ ⇌ R₂OsO₂·(L)+L is adjustable by vacuum (right) and pyridine (left). The dimethyl complex (CH₃)₂OsO₂·C₅H₅N, albeit monomeric in solution, has a trinuclear structure (Os₃O₃ core geometry) in the crystal, while the formally analogous derivative [(CH₃)₃SiCH₂]₂OsO₂·C₅H₅N is monomeric, displaying a strongly distorted trigonal-bipyramidal geometry (O-Os-O′ angle 141.3(4)°/141.7(4)°). All four complexes R₂OsO₂·(C₅H₅N)₂ (R = CH₃, 3a; CH₂Si(CH₃)₃, 3b and R₂OsO₂·(C₅H₅N) (R = CH₃, 4a; CH₂Si(CH₃)₃, 4b) were characterized by means of single-crystal X-ray diffraction techniques.
