In the title complex, [V(C(18)H(11)ClN(2)O(2))(CH(3)O)O(CH(3)OH)], the V(V) ion is coordinated by a tridendate 3-chloro-N'-(2-oxidonaphthalen-1-ylmethylidene)benzohydrazidate ligand, one oxido ligand and by O atoms from a methanol and a methoxide ligand, forming a distorted octa-hedral geometry. The dihedral angle between the benzene ring and the naphthyl-ene ring system is 6.4 (3)°. The deviation of the V(V) ion from the plane defined by the three donor atoms of the tridentate ligand and the meth-oxy O atom towards the oxido O atom is 0.323 (2) Å. In the crystal, pairs of inter-molecular O-H⋯N hydrogen bonds form centrosymmetric dimers.
