In the title compound, [Cu(C(19)H(16)Br(4)N(2)O(2))], the Cu(II) ion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the Cu(II) ion is distorted square-planar, which is defined by the N(2)O(2) donor atoms of the coordinated Schiff base ligand. The dihedral angle between the symmetry-related substituted benzene rings is 25.33 (14)°. The crystal structure is stabilized by an inter-molecular π-π inter-action [centroid-centroid distance = 3.8891 (18) Å].
在标题化合物[Cu(C₁₉H₁₆Br₄N₂O₂)]中,Cu(II)离子和二胺片段的取代C原子位于一个晶体学二重旋转轴上。Cu(II)离子周围的几何构型为扭曲的平面正方形,由配位席夫碱配体的N₂O₂供体原子确定。对称相关的取代苯环之间的二面角为25.33 (14)°。晶体结构通过分子间的π-π相互作用[质心-质心距离 = 3.8891 (18) Å]得以稳定。
