Abstract

As a final structural point it is noted that the bridging hydride occupies a coordination position on the Mo atom; therefore, the C ~ MO ( CO ) ~ ( H ) [P(X)(Y)] fragment should be considered as a four-legged piano stool. The average M-CO distance, 1.963 A, and OC - M d O angle, 78.5 (2O), compare favorably with the respective parameters in other C~MO(CO)~L, complexes.25 The bonding in 3 has been examined with extended Hiickel calculationsz6 which reveal ...
