Evidence for the existence of these π-acceptor semibridging carbonyl ligands is given by: (1) abnormally small Mo(2)C(2)O(2) and Mo(2)C(4)O(4) bond angles of 157.6(5) and 158.6(6)°, respectively; (2) the sharply acute Mo(1)Mo(2)C(2) and Mo(3)Mo(2)C(4) bond angles of 58.9(2) and 59.6(2)°, respectively; and (3) the relatively short carbonyl carbon distance to the second metal atom of 2.535(7) Å for the C(2) … Mo(1) interaction and 2.559(7) Å for the C(4) … Mo(3) interaction. These values are entirely consistent with the structural data recently tabulated by Crabtree and Lavin [15] in their detailed analysis of the bent semibridging carbonyl ligand.
