The structures of dichloro[2-[(5-methyl-1H-pyrazol-3-yl-kappaN(2))methyl]-1H-1,3-benzimidazole-kappaN(3)]copper(II), [CuCl(2)(C(12)H(12)N(4))], and di-mu-chloro-bis(chloro[2-[(5-methyl-1H-pyrazol-3-yl-kappaN(2))methyl]-1H-1,3-benzimidazole-kappaN(3)]cadmium(II)), [Cd(2)Cl(4)(C(12)H(12)N(4))(2)], show that these compounds have the structural formula ML(Cl)(2), where L is 2-[(5-methylpyrazolyl)methyl]benzimidazole. When M is copper, the complex is a monomer (n = 1), with a tetrahedral coordination for the Cu atom. When M is cadmium (n = 2), the complex lies about an inversion centre giving rise to a centrosymmetric dimer in which the Cd atoms are bridged by two chloride ions and are pentacoordinated.
二氯[2-[(5-甲基-1H-吡唑-3-基-κN(2))甲基]-1H-1,3-苯并咪唑-κN(3)]铜(II)，[CuCl₂(C₁₂H₁₂N₄)]，以及二-μ-氯-双(氯[2-[(5-甲基-1H-吡唑-3-基-κN(2))甲基]-1H-1,3-苯并咪唑-κN(3)]镉(II))，[Cd₂Cl₄(C₁₂H₁₂N₄)₂]，表明这些化合物具有结构式[ML(Cl)₂]ₙ，其中L为2-[(5-甲基吡唑基)甲基]苯并咪唑。当M为铜时，该配合物为单体(n = 1)，铜原子具有四面体配位。当M为镉时(n = 2)，该配合物位于一个对称中心上，形成一个中心对称的二聚体，其中镉原子由两个氯离子桥连且为五配位。
