The title compound has been synthesized under nitrogen atmosphere using V_2O_5 for the initiator by Schlenk techniques. It′s single crystal, which is very air and water-sensitive, was obtained and determined from three-dimensinal x-ray diffraction data collected by the four-circle diffractometer. The crystals are orth- orhombic with space group D_2~4-P_(212121) and unit cell constants a=0.909 nm, b=1.4909 nm, c=2.1635 nm and z=4.
We derived first the positional parameters of V, Zn, Cland O atoms by direct method using SHELXTL program. The coordinates of other the non-hyleast-squares refinement for all atoms gave a final discrepency factor R=0.0945 and RW=0.0674.
The result of structure analysis shows that the compound is composed of the octahedral cation [VCl_2·(THF)_4]~+ and the tetrahedral anion [ZnCl_3·THF]~-.
The reaction mechanism was discussed. The title compound is reaction product of VCl_3 with ZnCl_2 in THF.
