The geometric structures of the mixed chlorofluorophosphoranes PClnF5-n with n = 1-4 have been determined by gas electron diffraction. P-F and P-Cl bonds lengthen with increasing F/Cl substitution, whereby in general axial bonds are more strongly affected. Angular distortions from the ideal trigonal bipyramid are small, less than 1° for equatorial-axial angles and about 2° for equatorial-equatorial angles. Normal-coordinate analyses for the title compounds based on matrix infrared spectra and Raman polarization measurements (liquid) yield consistent sets of valence force constants, which reflect the trends in structural changes in this series. In the course of these normal-coordinate analyses it has been necessary to change some assignments found in the literature.
