✦ Synopsis

The Hartree-Fock instabilities of S2N2 are reported and compared with those of S3N3 and S4Ng'. These unsaturated sulfur nitrogen planar rings are P electron rich and although the symmetry adapted HF solutions are singlet stable at the experimental bond lengths they become unstable with only a very modest increase in bond length. The broken symmetry solutions for S2N3, S3N3, and S4N42' are of planar CZu type with one of the nitrogens stripped of its P electrons, producing a rr hole.
