Synthesis and characterization of CO{sub 2}-bridged bimetallic compounds derived from a rhenium metallocarboxylate. Correlation of IR spectral data with coordination geometry and bonding type
- Univ. of Louisville., KY (United States)
The synthesis and characterization of CO{sub 2}-bridged complexes, Cp{sup *}Re(CO)(NO)(CO{sub 2})M (3, M = Re(CO){sub 5}; 5 M = MO(CO){sub 2}Cp; 7, M = W(CO){sub 3}Cp; 8, M = W(CO){sub 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}{sub 2}-{eta}{sup 3}-CO{sub 2} complexes characterized recently, show that the coordination geometry at the metal center which anchors the carboxyl oxygens determines the position of the v{sub sym} band of the CO{sub 2} ligand. The position of the v{sub sym} band in these compounds varies only slightly and is determined by the metallocarboxylate group. 10 refs., 2 figs., 4 tabs.
