In the title complex, [Ni(CHClNO)(CHN)], the Ni ion is coordinated by two O atoms and one N atom derived from the dianionic '-[(1)-1-(5-chloro-2-hy-droxy-phen-yl)ethyl-idene]-4-meth-oxy-benzohydrazide ligand and one N atom from the imidazole mol-ecule. The NO donor set defines an approximate square-planar geometry. The dihedral angles between the imidazole ring and the fused six-membered and meth-oxy-benzene rings are 17.78 (14) and 13.23 (16)°, respectively; the dihedral angle between the C rings is 6.63 (12)°. The most prominent feature of the mol-ecular packing is the formation of 4-helical chains (along the axis) mediated by imidazole-N-H⋯O(phenoxide) hydrogen bonding; these are linked by methyl-C-H⋯Cl inter-actions.
在标题配合物[Ni(CHClNO)(CHN)]中,镍离子由二价阴离子[-[(1)-1-(5-氯-2-羟基苯基)亚乙基]-4-甲氧基苯甲酰肼]配体衍生的两个氧原子和一个氮原子以及咪唑分子的一个氮原子配位。NO供体组合定义了一个近似的平面正方形几何构型。咪唑环与稠合的六元环和甲氧基苯环之间的二面角分别为17.78 (14)°和13.23 (16)°;C环之间的二面角为6.63 (12)°。分子堆积的最显著特征是由咪唑-N-H⋯O(酚盐)氢键介导形成4-螺旋链(沿轴);这些链通过甲基-C-H⋯Cl相互作用相连。
