A second monoclinic polymorph of N-(diethyl­amino­thio­carbon­yl)-N′-phenyl­benzamidine

The asymmetric unit of the title compound, C(18)H(21)N(3)S, contains five mol­ecules. The equivalent bond distances in the five mol­ecules are in excellent agreement, the r.m.s. fit being within 0.007 Å. The five mol­ecules are linked into a chain consisting of alternating pseudo-enanti­omers by N—H...

Descripción
Sumario:The asymmetric unit of the title compound, C(18)H(21)N(3)S, contains five mol­ecules. The equivalent bond distances in the five mol­ecules are in excellent agreement, the r.m.s. fit being within 0.007 Å. The five mol­ecules are linked into a chain consisting of alternating pseudo-enanti­omers by N—H⋯S hydrogen bonds supplemented by weak C—H⋯π inter­actions. The action of a glide plane links the asymmetric unit into an extended chain. A polymorph of the title compound with one mol­ecule in the asymmetric unit was reported by Braun et al. [Cryst. Res. Technol. (1988), 23, 35–39].
