In the title compound, [Ni(C(22)H(17)BrN(2)O(4))]·CH(3)OH, the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The asymmetric unit contains one nickel complex and one methanol solvent mol-ecule. The dihedral angle between the aromatic ring planes of the central aromatic ring and other two aromatic rings are 10.8 (3) and 6.0 (2)°. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯Br and by intra-molecular O-H⋯O hydrogen bonds.
在标题化合物[Ni(C₂₂H₁₇BrN₂O₄)]·CH₃OH中,Ni(II)离子处于略微扭曲的平面正方形几何构型,涉及四齿席夫碱配体的N₂O₂原子集。不对称单元包含一个镍配合物和一个甲醇溶剂分子。中心芳香环与其他两个芳香环的芳香环平面之间的二面角分别为10.8 (3)°和6.0 (2)°。晶体结构通过分子间C—H⋯O和C—H⋯Br以及分子内O—H⋯O氢键得以稳定。
