In the title compound, [Cu(C(12)H(9)N(2)O)(2)], the Cu(II) atom lies on a crystallographic inversion center and has a nearly square-planar geometry. The Cu(II) center coordinates to the phenolic O and azomethine N atoms of the two symmetry-related 2-[(2-pyrid-yl)imino-meth-yl]phenolate ligands. The pyridyl N atoms do not coordinate to the Cu(II) atom but participate in intra-molecular C-H⋯N hydrogen bonding. π-π stacking between the benzene rings and between the pyridyl rings [centroid-centroid distances 3.8142 (5) and 3.8142 (5) Å, respectively] links the mol-ecules into a chain propagating parallel to [100].
在标题化合物[Cu(C₁₂H₉N₂O)₂]中,Cu(II)原子位于一个晶体学反演中心,具有近乎平面正方形的几何构型。Cu(II)中心与两个对称相关的2-[(2-吡啶基)亚氨基甲基]酚盐配体的酚羟基O原子和偶氮甲碱N原子配位。吡啶基N原子不与Cu(II)原子配位,但参与分子内C-H⋯N氢键作用。苯环之间以及吡啶环之间的π-π堆积作用[质心-质心距离分别为3.8142 (5) 和3.8142 (5) Å]将分子连接成平行于[100]方向延伸的链。
