摘要：

The synthesis and characterization of CO2-bridged complexes, Cp*Re(CO)(NO)(CO2)M (3, M = Re(CO)(5); 5, M = Mo(CO)(2)Cp; 7, M = W(CO)(3)Cp; 8, M = W(CO)(2)Cp) are described. Compound 5 has been structurally characterized. The geometry about the molybdenum atom in 5 is square-based pyramidal. All compounds have been characterized by DRIFTS IR spectral data. These data, together with DRIFTS and structural data from other symmetrical mu(2)-eta(3)-CO2 complexes characterized recently, show that the coordination geometry at the metal center which anchors the carboxyl oxygens determines the position of the nu(asym) band of the CO2 ligand. The position of the nu(sym) band in these compounds varies only slightly and is determined by the metallocarboxylate group.
