Abstract:
The title compound, C16H14N4S2, crystallizes in symmetry group C2. The molecule is planar with C2h symmetry, with the inversion centre at the mid-point of the hydrazine N-N bond, and it has an N-N s-trans conformation and a Z,Z configuration. The particular crystal examined was a racemic twin, as suggested by the Flack parameter of 0.41 (2) [Flack (1983). Acta Cryst. A39, 876-881].
