Abstract

It seems that the relative stability of the E2O2 and E2N2 (E=P,As) rings is mainly determined by the different weights of the oxygen and nitrogen p orbitals to the HOMO's of these systems which in turn reflects a more favourable orbital mixing in the rings where the difference of the electronegativity of the constituents is smaller. This might explain the great diversity of the cyclodiphosphazane (arsazane) rings comparatively to the cyclodiphosphoxane (arsoxane) rings.
