Abstract: The title compound, [V₂(C₁₃H₁₆N₃O₃)₂O₄]·2C₂H₆OS, is a centrosymmetric dimeric complex solvated by two dimethyl sulfoxide molecules. Each V^V atom is six-coordinated by one oxide group, two N atoms and one O atom from the tridentate Schiff base ligand, and by two additional bridging O atoms in a distorted octahedral coordination geometry. Three atoms of the cyclohexane ring are each disordered over two sites, with occupancy factors of 0.501 (10) and 0.499 (10). C-HO and N-HO hydrogen bonds link the dimers and solvent molecules into a supramolecular network.
