Abstract

In the title molecular salt, C(31)H(34)N(4) (2+)·2Br(-), the central benzene ring makes dihedral angles of 80.47 (12) and 82.78 (12)° with the adjacent imidazole rings. The dihedral angle between the two terminal phenyl rings is 79.16 (13)°. In the crystal, the cations and anions are linked via C-H⋯Br hydrogen bonds, forming supra-molecular chains along the c axis.

摘要

在标题分子盐C(31)H(34)N(4)(2+)·2Br(-)中，中心苯环与相邻的咪唑环形成的二面角分别为80.47 (12)°和82.78 (12)°。两个末端苯环之间的二面角为79.16 (13)°。在晶体中，阳离子和阴离子通过C—H⋯Br氢键相连，沿c轴形成超分子链。
