Abstract
Reaction of the alkyne-substituted cluster anion [Os3(CO)9(R1CCR2)]2- with the cation [Os(η6-C6H6)(CH3CN)]2+ affords the neutral tetranuclear cluster Os4(CO)9(η6-C6H6)(R1CCR2) (R1=R2=Me (1a); R1=Me, R2=Ph (1b); R1=R2=Ph (1c)). The structure of 1a has been confirmed by a single-crystal X-ray analysis. The metals adopt a 'butterfly' geometry with the alkylenic CC vector parallel to the 'hinge' vector of the 'butterfly', and the η6-C6H6 ligand occupies a terminal site on one of the 'wingtip' Os atoms. Complexes 1a and 1b may also be prepared by the reaction of the activated arene cluster Os4H2(CO)9(η6-C6H6)(CH3CN) with MeCCMe and MeCCPh, respectively. Under similar reaction conditions, with PhCCPh, the arene and acetonitrile ligands are substituted by the alkyne to give the known complex Os4H2(CO)9(PhCCPh)2 (2c).
