Crystal structure of bis-[μ-2-(diiso-propyl-phosphor-yl)propan-2-olato-κ(3) O (1),O (2):O (1)]bis-[chlorido-oxidovanadium(IV)].
The dinuclear mol-ecule of the title complex, [VOCl{μ-OC(Me)2P(iPr)2-κ(2) O}]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-(diiso-propyl-phosphor-yl)propan-2-olate dianions. The V(IV) 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 intra-molecular C-H⋯Cl contact helps to establish the mol-ecular configuration. In the crystal, mol-ecules are stacked in rows parallel to [001] and are linked by C-H⋯Cl contacts to form chains running in the same direction.
