SYSTEMATIC SYNTHESIS AND CHARACTERISATION OF PHOSPHIDO-BRIDGED TRIOSMIUM CARBONYL CLUSTERS

Article abstract of DOI:10.1016/0022-328X(85)80358-2

Phosphine-substituted triosmium clusters Os3(CO)11PR¹R²H (a: R¹=R²=H; b: R¹=Ph, R²=H; c: R¹,R²=Ph) have been found to yield, via a deprotonation/protonation sequence, the phosphido-bridged clusters (μ-H)Os3(CO)10-(μ-PR¹R²): the intermediate anions <(Os3(CO)10(μ-PR¹R²))^-> and <((μ-H)Os3(CO)10(μPR¹))^-> in this systematic synthesis are described.
