Abstract: A new monoclinic polymorph of the title compound, [V₂(C₁₀H₁₃N₂O)₂O₄], which is a centrosymmetric dimer, crystallizes in space group P2₁/c, whereas the previously known polymorph crystallizes in the orthorhombic space group Pbca [Mokry & Carrano (1993). Inorg. Chem. 32, 6119-6121]. Each V^V atom is six-coordinated by one oxide group, two N atoms and one O atom from the Schiff base ligand, and by two additional bridging O atoms. The two methylene groups are each disordered over two sites, with occupancy factors of 0.776 (14) and 0.224 (14). In the crystal structure, there are C-HO hydrogen bonds and C-H interactions between the dimers.
