Abstract
<jats:p>The crystal and molecular structures of Os3(µ3-Me3SiC2C=CSiMe3)(µ-OMe)2(CO)9, obtained serendipitously from a reaction between complex Os3(µ3-Me3SiC2C=CSiMe3)(µ-CO)(CO)9 and OsBr(PPh3)2Cp, are reported. The Os3 cluster core has opened as a result of one CO ligand being replaced by two OMe groups to form a 52-electron complex with only one Os–Os bond. The two non-bonded Os–Os vectors are each bridged by an OMe group, while the geometry of the C2Os3 fragment is little changed from that found in Os3 (3-PhC2C=CPh)(-CO)(CO)9.</jats:p>
