The title compound, [Sb(C(6)H(5))(3)(N(2)S(2))], contains a molecular entity that is very similar to that of the known polymorph of Sb(S(2)N(2))Ph(3) [Kunkel et al. (1997 ▶). Z. Naturforsch. Teil B, 52, 193-198], differing only in the orientation of the phenyl rings. The bond order in the SNSN unit is S-N=S=N, consisting of one long S-N bond, an inter-mediate length N=S bond and a short S=N bond.
