Abstract
The dinuclear molecule of the title complex, [VOCl{μ-OC(Me)2P(iPr)2-κ2O}]2 or [V2(C9H20O2P)2Cl2O2], which was obtained due to an unexpected oxidation reaction, is centrosymmetric, with the inversion centre located in the middle of the central V2O2 core. These core O atoms arise from the symmetry-related 2-(diisopropylphosphoryl)propan-2-olate dianions. The VIV atom is additionally bonded to one terminal Cl ligand, the second O atom of the dianion and double bonded to a vanadyl O atom, leading to an overall distorted square-pyramidal VO4Cl coordination polyhedron with the vanadyl O atom as the apex. An intramolecular C—H⋯Cl contact helps to establish the molecular configuration. In the crystal, molecules are stacked in rows parallel to [001] and are linked by C—H⋯Cl contacts to form chains running in the same direction.
