The title compound, C(12)H(12)N(4)O(2)S, crystallizes with Z' = 2 in space group P2(1)/c. The intramolecular dimensions are consistent with a highly polarized electronic structure. Each of the independent molecules forms a centrosymmetric dimer linked by paired N-H.N hydrogen bonds, and these dimers are linked into a single type of chain by aromatic pi-pi-stacking interactions.
标题化合物C(12)H(12)N(4)O(2)S以Z' = 2的形式结晶于空间群P2(1)/c中。分子内尺寸与高度极化的电子结构一致。每个独立分子通过成对的N-H.N氢键形成一个中心对称二聚体,并且这些二聚体通过芳香π-π堆积相互作用连接成单一类型的链。
