Infrared absorption spectra of four (ethylbenzoyl acetate) [EBA] complexes of trivalent samarium of the general formula XpSm(EBA)q [X = isopropoxy or t-butoxy group; when p=1, q=2 and vice versa] have been studied in the region 4000-250 cm-1 for the first time. About twenty five bands in each complex have been observed and assigned to different modes of vibration. The separation between asymmetric and symmetric CO stretching vibrations indicates that the bonding in all the complexes is nearly the same. The spectra show that the interaction between the two ligand rings is small in five coordinated metal complexes.
