Vibrational analysis of metal diimine dithiolate mixed ligand complexes

Abstract

The IR spectra of the M(mnt)(baba) where M = Ni and Pd, mnt = 1,2-maleonitrile and baba = biacetylbisanyline, were recorded in the high as well in the low energy region. A complete assignment of the observed bands was performed based on well-documented references. Further, a normal coordinate analysis was carried out taking into account C2υ symmetry, and based in a simplified model in order to investigate the force field of both metal complexes and the potential energy distribution (PED) of the distinct modes of the quelate structure. © 1999 Elsevier Science B.V.
