The postulated transition of Bis-Maltolato-OxoVanadium(IV) (BMOV) from its inactive trans- into its cis-aquo-BMOV isomeric form in solution was simulated by means of computational molecular modeling. The rotational barrier was calculated with DFT - B3LYP under a stepwise optimization protocol with STO-3G, 3-21G, 3-21G*, and 6-31G ab initio basis sets. Our computed results are consistent with re...

The oxovanadium(IV) complex of formula [VOCl(H2biim)2]Cl (H2biim=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(H2biim)2] + cations and Cl anions, linked together by N H···Cl···H N hydrogen bonds. The vanadium atom lies in a very dist...
