|Title:||Raman And Infrared Spectra And Normal Coordinate Analyses Of Zirconium And Hafnium Tetrachloride Complexes With Phosphoryl Chloride, Zrcl4·2pocl3 And Hfcl4·2pocl3|
|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.|
