Y. Hase et Ol. Alves, VIBRATIONAL AND AM1 STUDY OF THE MOLECULAR-STRUCTURE OF HEXAKIS(BENZONITRILE) COMPLEX-IONS [M(BN)(6)](2+), Vibrational spectroscopy, 6(2), 1994, pp. 225-228
The Raman and IR spectra of [M(BN)(6)](2+), where M = Mn, Co, Ni and Z
n, and BN = benzonitrile, have been obtained in the C=N stretching reg
ion. The band splittings of the C=N fundamentals were observed for the
first time and interpreted as the T-h --> S-6 --> D-3d symmetry chang
e of the molecular structure in accordance with AM1 molecular orbital
calculations.
