Raman and infrared spectroscopic studies of tris triphenyl phosphine chloride complexes of transition metals

In this work for the first time, Raman spectra are presented of tris triphenyl phosphine cobalt(I) chloride and tris triphenyl phosphine ruthenium(II) chloride. Infrared spectra are also provided for these complexes and infrared and Raman spectra of tris triphenyl phosphine copper(I) chloride are also provided for comparison. Assignments are made of the phosphine ligand vibrations in the vibrational spectra of these complexes in comparison with the free ligand triphenyl phosphine which identify the MX and MP vibrations; assistance in the skeletal assignments is achieved by comparison with the complex tris triphenyl phosphine rhodium(I) chloride.
