A structural model for vanadyl–histidine interactions: structure determination of [VO(1-vinylimidazole)4Cl]Cl by a combination of X-ray crystallography and X-ray absorption spectroscopy

[VO(1-vinylimidazole)4Cl]Cl is prepared and spectroscopically characterized and structural information obtained from vanadium K-edge EXAFS used to solve a disorder problem encountered in the refinement of the crystal structure; oxovanadium(IV) bound to imidazole groups has relevance to the possible biochemical functions of vanadium.
