In the title compound, [Cu(C(20)H(12)Br(2)N(2)O(2))(CH(3)OH)], the Cu(II) ion, and the C, O and hydr-oxy H atoms of the coordinated methanol mol-ecule are located on a twofold rotation axis, while the methyl H atoms are disordered over two sites about the rotation axis. The Cu(II) ion is coordinated by two N atoms [Cu-N = 1.960 (4) Å] and two O atoms [Cu-O = 1.908 (4) Å] from the tetra-dentate Schiff base ligand and by one O atom [Cu-O = 2.324 (6) Å] of the methanol molecule in a square-pyramidal geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link complex mol-ecules into extended chains along [001].
在标题化合物[Cu(C₂₀H₁₂Br₂N₂O₂)(CH₃OH)]中,Cu(II)离子以及配位甲醇分子的C、O和羟基H原子位于一个二重旋转轴上,而甲基H原子围绕旋转轴在两个位置上无序分布。Cu(II)离子由四齿席夫碱配体的两个N原子[Cu-N = 1.960 (4) Å]和两个O原子[Cu-O = 1.908 (4) Å]以及甲醇分子的一个O原子[Cu-O = 2.324 (6) Å]配位,呈四方锥几何构型。在晶体结构中,分子间的O-H⋯O氢键将配合物分子沿[001]方向连接成延伸的链。
