In the title complex, [Cu(C22H17Br2N2O2)2], the Cu(II) ion is four-coordinated in a trans-CuN2O2 square-planar geometry by two phenolate O and two imino N atoms from two deprotonated N,O-bidentate ligands. In the crystal, the packing of the mol-ecules is controlled by C-H⋯π and π-π inter-actions [centroid-centroid distances = 3.568 (3), 3.678 (2), 3.717 (3) and 3.799 (2) Å] and weak Br⋯Br halogen bonds [3.508 (4) Å], linking the mol-ecules into an infinite three-dimensional supra-molecular network.
在标题配合物[Cu(C₂₂H₁₇Br₂N₂O₂)₂]中，Cu(II)离子通过来自两个去质子化的N,O-双齿配体的两个酚氧原子O和两个亚氨基氮原子N，以反式-CuN₂O₂平面正方形几何构型进行四配位。在晶体中，分子堆积由C-H⋯π和π-π相互作用[质心-质心距离 = 3.568 (3)、3.678 (2)、3.717 (3)和3.799 (2) Å]以及弱的Br⋯Br卤键[3.508 (4) Å]控制，将分子连接成一个无限的三维超分子网络。
