A DIVANADIUM(III) COMPLEX BRIDGED BY CL- AND OH- ANIONS

The crystal structure of the complex mu-chloro-mu-hydroxo-bis [dichlor obis(tetrahydrofuran-O)vanadium(III)] tetrahydrofuran solvate, [V-2(mu -Cl)(mu-OH)Cl-4(thf)(4)].thf (where thf is tetrahydrofuran, C4H8O), wa s determined. It was obtained from a tetrahydrofuran solution containi ng [VCl3(thf)(3)] and NaCPh(3). The two octahedral vanadium(III) cente rs are bridged by a Cl- and an OH- anion, with a V ... V separation of 3.281(1)Angstrom. One vanadium(III) center has two axial Cl and two e quatorial tetrahydrofuran ligands, while the other vanadium(III) cente r has two axial tetrahydrofuran and two equatorial Cl Ligands, A tetra hydrofuran molecule which is contained as crystalline solvent is invol ved in hydrogen bonding with the bridging OH- anion.
