Abstract
The structure of bis[P,P-di-tert-butyl-N-(di-tert-butylphosphorothioyl)phosphinimidothioato-κS]sulfur(II) toluene solvate (systematic name: 5,13-dibutyl-7,7,11,11-tetramethyl-8,9,10-trithia-6,12-diaza-5λ(5),7λ(5),11λ(5),13λ(5)-tetraphosphaheptadeca-6,11-diene-5,13-dithione toluene solvate), C(32)H(72)N(2)P(4)S(5)·C(7)H(8), at 173 K has monoclinic (C2/c) symmetry. The S(II) centre of (SP(t)Bu(2)NP(t)Bu(2)PS-)(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 Å 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)°. The toluene solvent molecule is disordered about a twofold axis.
