Abstract

Solid state X-ray photoelectron spectra of S2N2, S4N4, (SNBr0.04)x, and (SNBr0.25)x have been obtained and the gas phase spectrum of S2N2 is also reported. Both the solid state and gas phase core level spectra, as well as MNDO and CHELEQ calculations, show that there is greater S → N charge transfer in S4N4 than in S2N2. The solid state data indicate that the charge distributions in S2N2 and (SN)x are the same. All of the data can be satisfactorily explained without recourse to N pπ → S dπ bonding. Bromination of an (SN)x film and single crystals results in complicated, broad N 1s and S 2p envelopes. Changes in the relative core level intensities on bromination suggest that the bromine resides largely between and/or on the (SN)x fibrils, rather than penetrating into the fibrils.
