| Abstract: | The reaction of the 'benzyne' cluster Os3H2(CO)9(C6H4) with diphenylacetylene affords the new compound Os3(CO)7(C6H4)PhCC(H)Ph]2; a single crystal X-ray analysis of this product shows that two PhCC(H)Ph units and the benzyne moiety are bonded to the Os3 core as separate ligands, and that under these conditions there is no ligand condensation. |
