Triaqua(2,2'-biimidazole)oxovanadium(IV) sulfate dihydrate

R. Sang, M. Zhu and P. Yang

Abstract: The V atom in the oxovanadium(IV) complex [VO(H₂biim)(H₂O)₃]SO₄·2H₂O, with a non-deprotonated 2,2'-biimidazole ligand (H₂biim, C₆H₆N₄), has a distorted octahedral coordination with the vanadyl O atom in a trans position with respect to one of the water molecules. The N-V-N angle within the five-membered chelate ring is the smallest in the coordination octahedron [78.66  (12)°]; the angles involving the vanadyl bond are somewhat wider than the corresponding angles involving the trans V-O(OH₂) coordination bond.
