Abstract
The vibrational Raman and i.r. spectra of 1:2 molecular complexes of ZrCl4 and HfCl4 with phosphoryl chloride have been recorded in the regions 4000-50 cm-1 and 4000-180 cm-1, respectively. The observed spectral data for powder samples have been analysed by comparison with those of related compounds and the resulting assignments have confirmed their octahedral cis-configurations with two non-equivalent POCl3 ligands. The normal coordinate calculations have been studied to obtain the Urey-Bradley force constants and the potential energy distribution. © 1981. 37 11 957 963 Kawano, Gushikem, Hase, (1977) J. Mol.
