Di-μ-chlorido-bis-[diacetonitrile-chlorido-oxidovanadium(IV)].

The title compound, [V2Cl4O2(CH3CN)4], is a centrosymmetric dinuclear VIV complex associated with four mol­ecules of acetonitrile. The coordination around both VIV atoms is essentially square-planar, involving three Cl atoms and one O atom [maximum deviation = 0.017 (3) A for the O atom]. The augmented octahedral coordination of the metal atom is completed by the N atoms of acetonitrile ligands. The VIV atoms are linked by two Cl atoms, acting as bridging atoms. The crystal studied was a non-merohedral twin with a ratio of the two twin components of 0.8200 (3):0.1800 (3). Although Cl and O atoms are present as potential acceptors in the title compound, no hydrogen bonds were observed in the crystal structure.
