摘要：

The oxovanadium(IV) complex of formula [VOCl(H(2)biim)(2)]Cl (H(2)biim = 2,2'-biimidazole) has been prepared and characterized by chemical analysis, single crystal X-ray diffraction, and IR and electronic spectroscopies. The crystal structure consists of chains of alternating [VOCl(H(2)biim)(2)](+) cations and Cl- anions, linked together by N-H . . . Cl-. . .H-N hydrogen bonds. The vanadium atom lies in a very distorted octahedral coordination. The magnetic moment and the EPR signal correspond to a d(1) configuration without any magnetic interaction.
