The structure of bis[P,P-di-tert-butyl-N-(di-tert-butylphosphorothioyl)phosphinimidothioato-kappa S]sulfur(II) toluene solvate (systematic name: 5,13-dibutyl-7,7,11,11-tetramethyl-8,9,10-trithia-6,12-diaza-5 lambda 5,7 lambda 5,11 lambda 5,13 lambda 5-tetraphosphaheptadeca-6,11-diene-5,13-dithione toluene solvate), C32H72N2P4S5 center dot C7H8, at 173 K has monoclinic (C2/c) symmetry. The SII centre of (SP t Bu2NP t Bu2PS-)(2)S is coordinated in an S-monodentate fashion to two [(SP t Bu-2)(2)N]- monoanions. The molecule resides on a twofold axis which bisects the central S atom. The internal P-S distance is ca 0.19 A longer than the terminal P=S bond and there is a compensating alternation in P-N bond distances. The central S-S-S angle is 106.79 (8)degrees. The toluene solvent molecule is disordered about a twofold axis.
