The V(V) atom in the title complex, [V(C(14)H(8)BrClN(2)O(2))(CH(3)O)O(CH(3)OH)], is six-coordinated by one phenolate O, one imine N and one enolic O atom of the hydrazone ligand, one oxide O atom, one methanol O atom and one methoxide O atom in a distorted octa-hedral geometry. The dihedral angle between the two benzene rings of the hydrazone ligand is 13.2 (3)°. The deviation of the V atom towards the oxide O atom from the plane defined by the three donor atoms of the hydrazone ligand and the meth-oxy O atom is 0.318 (2) Å. Bond lengths are comparable with those observed in similar oxidovanadium(V) complexes with hydrazone ligands. In the crystal, pairs of mol-ecules are linked through inter-molecular O-H⋯N hydrogen bonds, forming dimers.
在标题配合物[V(C₁₄H₈BrClN₂O₂)(CH₃O)O(CH₃OH)]中，V(V)原子由腙配体的一个酚氧原子、一个亚胺氮原子和一个烯醇氧原子、一个氧化物氧原子、一个甲醇氧原子和一个甲氧基氧原子以扭曲的八面体几何构型进行六配位。腙配体的两个苯环之间的二面角为13.2 (3)°。V原子相对于氧化物氧原子偏离由腙配体的三个供体原子和甲氧基氧原子所定义平面的距离为0.318 (2) Å。键长与在具有腙配体的类似氧化钒(V)配合物中观察到的键长相当。在晶体中，分子对通过分子间的O—H⋯N氢键相连，形成二聚体。
