Abstract

Title full: Preparation and characterisation of some mixed clusters of bismuth with osmium and ruthenium; crystal and molecular structures of Os3(μ-H)3(CO)93-Bi), Os4(CO)124-Bi)2, Ru3(μ-H)3(CO)93-Bi), and Ru4(CO)124-Bi)2. Reaction of NaBiO3 with Os3(CO)12 and a number of higher nuclearity osmium clusters affords a variety of bismuth-containing products, including Os3H3(CO)9Bi (1), Os3(CO)9Bi2 (2), and Os4(CO)12Bi2 (3). Under similar conditions, Ru3(CO)12 affords only low yields of Ru3H3(CO)9Bi (5), but better yields of Ru3H3(CO)9Bi (5), Ru3(CO)9Bi2 (6), Ru4(CO)12Bi2 (7), and Ru5H(CO)18Bi (8), are obtained by reaction of Bi(NO3)3 · 5H2O with the [Ru3H(CO)11]- anion. The structures of 1, 3, 5, and 7 have been established by X-ray diffraction; 1 and 5 are isostructural with the known iron analogue, while the metal frameworks in 3 and 7 display different isomeric forms of the M4Bi2 octahedron.
