摘要：

The heterometallic cluster compound (C5Me5)W(mu-O)(2)Os-3(mu-CCPh)(CO)(9) (1), which possesses true edge-bridging oxo groups and an acetylide ligand in a mu-eta(2) mode, has been obtained by addition of (C5Me5)W(O)(2)(CCPh) to Os-3(CO)(10)(NCMe)(2). The subsequent reactivity studies led to the isolation of Cp*W(mu-O)(2)Os-3(mu-H)(CO)(9) (2) and Cp*W(O)(mu-O)Os-3(CCPh)(CO)(9) (3) through hydrogenation and treatment with pressurized CO, respectively. The structures of 1 and 3 reveal two distinctive bonding modes for the (C5Me5)W(O)(2) fragment on an Os-3 skeleton.
