✦ Synopsis

The vibrational properties of the diphenylbismuth(II1) chloride compounds (C,H,),BiCI and [N(CH,),]'[(C,H,),BiC12]-have been investigated. A comprehensive assignment of the fundamental modes in the measured Fourier-transform Raman and infrared spectra has been carried out. Normal coordinate calculations of these compounds based on new X-ray crystal structure data have been performed to identify the Bi-CI stretching and bending vibrations of both compounds. For [N(CH,)4]'[(C&s)zBiC12]-in the solid state, the v.(BiClr) and v,(BiClr) occur at 215cm-' (Raman) and 237cm-' (Raman), respectively, in good agreement with the calculated wavenumbers. The force constant calculation yields a B&Cl stretching force constant of 0.89 x ld N m-l.
