Abstract

The asymmetric unit of the title compound, C(16)H(16)N(4)O(2)S, contains two mol-ecules (A and B) with similar conformations: the benzene rings are oriented at dihedral angles of 80.94 (10)° and 84.54 (10)° with their adjacent 1H-benzimidazole groups. In the crystal, the mol-ecules are connected by N-H⋯N hydrogen bonds, forming separate C(4) chains of both the A and B mol-ecules along [010]. The A and B chains are cross-linked by several C-H⋯O inter-actions involving the benzene rings and the sulfonyl groups, which lead to R(2) (1)(5) loops in the linkage of the chains.

摘要

标题化合物C(16)H(16)N(4)O(2)S的不对称单元包含两个构象相似的分子(A和B):苯环与其相邻的1H-苯并咪唑基团的二面角分别为80.94 (10)°和84.54 (10)°。在晶体中,分子通过N-H⋯N氢键相连,沿[010]方向形成A和B分子各自独立的C(4)链。A链和B链通过涉及苯环和磺酰基的多个C-H⋯O相互作用交联,在链的连接中形成R(2) (1)(5)环。
