Abstract
The FT-Raman and selected IR spectra of 14 heterobimetallic complexes of (CO) 3CrC 6H 5-C 5H 4M(CO) n (NO) m X (M = transition metal, X = other ligands) are reported. FT-Raman exhibits distinct strong characteristic bands of coordinated C 6H 5-C 5H 4 ligand ring deformation near 1540, 1490 and 1280 cm −1 and the coordinated phenyl ring deformation mode near 1000 cm −1, which are negligible in IR spectra. It is also easy to find the M-CO stretching and M-C-O bending as well as phenyl-M stretching bands in the FT-Raman spectra. The v(CO) IR absorptions in THF solution were reasonably assigned according to the local symmetry of the complexes.
