The infrared absorption of pentaphenylphosphorane in the 230-4000 cm-1 region was measured. Three bands in the 650-710 cm-1 region are considered to be due to fundamental PC stretching vibrations. These (in cyclohexane solution) are 655·8, 701·6 and 707·6 cm-1. Three such vibrations are expected with a simple square pyramidal structure (point group C4v), while a trigonal bipyramidal structure (point group D3h) would require only two infra-red active PC stretching modes.
