摘要：

The title compound is readily prepared from the rhenium carboxylate, (dppe) (CO)(3)ReC(O)OCH3, by prolonged stirring of a solution of the carboxylate in benzene/H2O or THF/H2O. The reaction involves the unusual in situ conversion of Re-C bonds to Re-O bonds. The X-ray structure of the title compound shows that the mu(2) eta(2)-carbonato ligand is present in the symmetrical syn, syn conformation in the solid state in contrast to the alternate syn, anti geometry reported for the related complex, (diars)(CO)(3)ReOC(O)ORe(CO)(3)(diars).
