摘要：

The substitution of the mu-acetato ligands in cis-Re-2(mu-O2CCH3)(2)-Cl-2(mu-dppm)(2) (1, dppm = Ph2PCH2PPh2) and trans-Re-2 (mu-O-2-CCH3)(2)Cl-2(mu-dppE)(2) (2, dppE = Ph2PC(=CH2)PPh2) by [4-Ph2PC6H4CO2](-) occurs with retention of stereochemistry to give cis-Re-2 (mu-O2CC6H4-4-PPh2)(2)Cl-2(mu-dppm)(2) (3) and trans-Re-2(mu-O2CC6H4-4 PPh2)(2)Cl-2(mu-dppE)(2) (6), respectively. The uncoordinated phosphine groups in complexes 3 and 6 have been used to form mixed-metal assemblies with Au(I) and Pd(II), including the Re2Pd2 complex cis-Re-2(mu-O2CC6H4-4-PPh2)(2)Cl-2(mu-dppm)(2)(Pd2Cl4) (5), in which the planar [(P)C\Pd(mu-Cl)(2)PdCl(P)] unit has the unusual cis structure. The crystal structures of 3 and 5 have been determined.
