The synthesis of the rhenium/main-group-metal bridging CO/sub 2/ or carboxylate complexes of the formula (eta/sup 5/-C/sub 5/H/sub 5/)Re(NO)(PPh/sub 3/)(CO/sub 2/ML/sub n/) where M = Li, K, Ge, Sn, or Pb from the rhenium carboxylic acid (eta/sup 5/-C/sub 5/H/sub 5/)Re(NO)(PPh/sub 3/)(COOH) is reported. The molecular structure of the complexes was investigated, and both monodentate and bidentate carboxylate binding modes were observed with the symmetrical bidentate binding in the tin complex being unprecedented. Clean thermal decarboxylation occurs when the main-group metal is tin or lead to provide a convenient route to the preparation of heterobimetallic complexes. 14 references, 1 figure.
