ResumoElectronic structure calculations for (SN)x suggest: (i) the dominant σ interchain interactions in a 102 plane are not due to S…S interactions; (ii) the interactions in a 102 plane lead to band splittings for the upper bands of about 1 eV for σ-type and 0.5 eV for π-type; (iii) the interaction in a 100 plane results primarily from π electrons yielding a splitting of the π bands of about 1 eV; (iv) the possibility of a novel effect associated with the Peierls instability.
