4,4′-Bis(benzimidazol-1-yl)biphenyl
نویسندگان
چکیده
The mol-ecule of the title compound, C(26)H(18)N(4), resides on a crystallographic inversion centre with a dihedral angle of 44.94 (5)° between the benzimidazole ring system and the benzene ring. The primary hydrogen bond is C-H⋯N and inversion-related pairs of these generate a chain of rings along the c-axis direction; π⋯π stacking involving the benzimidazole groups with inter-planar separations of ca 3.4 Å complete the inter-actions.

In the title compound, [CuCl(2)(C(26)H(18)N(4))](n), the Cu(II) ion is four-coordinated by two N atoms from two 4,4'-bis-(benzo-imidazol-1-yl)biphenyl ligands and two chloride anions, in a slightly distorted tetra-hedral environment. The biphenyl ligand acts as a linear bidentate ligand, connecting the metal atoms into an infinite chain parallel to [101]. In the biphenyl ligand, the two benzene...
