In the title compound, [Cu(C(19)H(18)Br(2)N(2)O(2))], the Cu(II) ion is in a tetra-hedrally distorted planar geometry, involving two N and two O atoms from the tetra-dentate Schiff base ligand. Inter-molecular C-H⋯O hydrogen bonds form an eight-membered R(2) (2)(8) motif. The dihedral angle betwen two benzene rings is 36.34 (9)°. There are inter-molecular Cu⋯Br [3.4566 (5) Å] and Cu⋯·N [3.569 (3) Å] contacts, which are significantly shorter than the sum of van der Waals radii of the relevant atoms. These inter-actions, along with the inter-molecular C-H⋯π and π-π [centroid-centroid distances of 3.709 (1) and 3.968 (2) Å] inter-actions, link neighbouring mol-ecules into a one-dimensional infinite chain along the c axis.
在标题化合物[Cu(C₁₉H₁₈Br₂N₂O₂)]中，Cu(II)离子处于四面体畸变的平面几何构型，涉及来自四齿席夫碱配体的两个N原子和两个O原子。分子间C—H⋯O氢键形成一个八元R₂²(8) motif。两个苯环之间的二面角为36.34 (9)°。存在分子间Cu⋯Br [3.4566 (5) Å]和Cu⋯N [3.569 (3) Å]接触，其明显短于相关原子范德华半径之和。这些相互作用，连同分子间C—H⋯π和π—π [质心间距分别为3.709 (1)和3.968 (2) Å]相互作用，将相邻分子沿c轴连接成一维无限链。
