Formation of cluster alkene complexes by nucleophilic attack on a vinyl hydride cluster: X-ray crystal structures of [(Ph3P)2N][Os3(CO)10{CF3(H)C:C(H)CF3}Br] and [Os3(CO)10{CF3(H)C:C(H)CF3}(PEt3)]

Abstract

[Os₃H(CO)₁₀{CF₃CCHCF₃}] reacts with certain 2-electron donor ligands, L, to give cluster alkene complexes [Os₃(CO)₁₀{CF₃(H)C:C(H)CF₃}L]; the X-ray structures of two of these complexes (L = Br^–, PEt₃) are reported.
