Abstract

Vapour phase HeI photoelectron spectra of the diphosphazane ligands RN (PX2)2 (R=CH3 or C6H5, X=Cl, OCH3 or OC6H5) are presented along with the assignments of bands on the basis of molecular orbital calculations. The spectra are in accordance with the structural studies which indicate multiple bonding in the P-N-P segment. The phosphorus lone pair ionization energy appears to follow the σ donor ability of the ligands.
