The title Schiff base complex, [V(C13H7BrClNO2)(CH3O)O(CH3OH)], features a vanadyl group, a tridentate Schiff base ligand, and coordinated methanol and methanolate ligands. The NO5 donor set is based on a distorted octahedron. Helical supramolecular chains along  are found in the crystal structure mediated by O—H⋯O hydrogen bonds formed between the coordinating methanol molecule and the phenolate O atom of the chlorobenzene residue.
