The title compound, C(13)H(10)Cl(2)N(2)S, represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Ramnathan et al. (1996 ▶). Acta Cryst. C52, 134-136]. The mol-ecule is twisted with the dihedral angle between the benzene rings being 55.37 (7)°. The N-H atoms are syn to each other, which contrasts their anti disposition in the ortho-rhom-bic form. In the crystal, mol-ecules assemble into zigzag chains along the c axis via N-H⋯S hydrogen bonds. Chains are connected into layers via C-H⋯Cl inter-actions, and these stack along the a axis.
标题化合物C(13)H(10)Cl(2)N(2)S是先前报道的正交晶型[Ramnathan等人,(1996 ▶)。《晶体学报》C52, 134 - 136]的单斜晶型多晶型物。分子呈扭曲状,苯环之间的二面角为55.37 (7)°。N - H原子彼此为顺式,这与它们在正交晶型中的反式排列形成对比。在晶体中,分子通过N - H⋯S氢键沿c轴组装成锯齿链。链通过C - H⋯Cl相互作用连接成层,并且这些层沿a轴堆叠。
