Abstract

In the title Schiff base complex, [Ni(C(18)H(14)Cl(4)N(2)O(2))(C(3)H(7)NO)(2)], the geometry around the Ni(II) atom is distorted octa-hedral. It is coordinated by the N(2)O(2) donor atoms of the tetra-dentate Schiff base ligand and the O atoms of two dimethyl-formamide mol-ecules, which are cis to one another. The benzene rings are almost normal to each other [dihedral angle = 88.60 (14)°]. The various intra-molecular C-H⋯O hydrogen bonds make S(5) and S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of weak C-H⋯Cl inter-actions, forming inversion dimers.

摘要

在席夫碱配合物[Ni(C₁₈H₁₄Cl₄N₂O₂)(C₃H₇NO)₂]的标题中，Ni(II)原子周围的几何构型为畸变八面体。它由四齿席夫碱配体的N₂O₂供体原子和两个彼此顺式的二甲基甲酰胺分子的O原子配位。苯环几乎相互垂直[二面角 = 88.60 (14)°]。各种分子内C—H⋯O氢键形成了S(5)和S(6)环模式。在晶体中，分子通过成对的弱C—H⋯Cl相互作用相连，形成反演二聚体。
