A Divanadium(III) Complex Bridged by Cl⁻ and OH⁻ Anions

The crystal structure of the complex μ-chloro-μ-hydroxo-bis[dichlorobis(tetrahydrofuran-O)vanadium(III)] tetrahydrofuran solvate, [V₂(μ-Cl)(μ-OH)Cl₄(thf)₄].thf (where thf is tetrahydrofuran, C₄H₈O), was determined. It was obtained from a tetrahydrofuran solution containing [VCl₃(thf)₃] and NaCPh₃. The two octahedral vanadium(III) centers are bridged by a Cl⁻ and an OH⁻ anion, with a V...V separation of 3.281 (1) Å. One vanadium(III) center has two axial Cl and two equatorial tetrahydrofuran ligands, while the other vanadium(III) center has two axial tetrahydrofuran and two equatorial Cl ligands. A tetrahydrofuran molecule which is contained as crystalline solvent is involved in hydrogen bonding with the bridging OH⁻ anion.
