The core electron binding energies of (NPF2)3, (NPF2)4, (NPCl2)3, (NPCl2)4, and [NP(CH3)2]4 have been determined in the gas phase by x-ray photoelectron spectroscopy. The data show a reasonable correlation with the elecronegativities of the substituent groups. On going from (NPF2)4 to (NPF2)3 or from (NPCl2)4 to (NPCl2)3, the binding energies increase by only 0.22 eV or less. This near-constancy of the binding energies suggests that the degree π bonding is similar in the trimers and tetramers.
