摘要
The molecular structure of Re-2(mu-2 eta(1),eta(4)-C(4)Ph(4))(CO)(7) obtained from Re-2(CO)(8)(NCMe), and C(2)Ph(2), consists of an Re-2(CO)(7) unit [Re-Re 2.874(1) Angstrom] bridged by a 2 eta(1),eta(4)-C(4)Ph(4) ligand, as proposed by earlier workers. Methyl propiolate is inserted into the Re-Re bond of Re-2(CO)(9)(NCMe), as shown by the molecular structure of the NMe(3) derivative of the product; the NMe(3) Ligand is attached to the non-chelated Re atom [Re-N 2.31(1) Angstrom].
