Abstract Vanadium(V) complex was synthesized in good yield and characterized by FT-IR, UV–Visible and NMR spectroscopy. The structure of the complex was confirmed by single X-ray crystallography. X-ray structural analysis the complex featuring O∙∙∙O chalcogen bonding interaction and other short interaction. The O∙∙∙O intermolecular interactions distance is 2.794 A. Clearly, the O∙∙∙O intermolecular distance in the O-linked complex is less than the sum of van der Waals atomic radii of oxygen 3.00 A (rvdW (O) = 1.50 A). Oxidations of cyclohexane to cyclohexanol were also carried out, using the synthetic complex as a catalyst. The catalytic studies were carried out successfully using m-chloroperbenzoic acid as oxidant at 100 °C, under solvents free conditions. The catalytic protocols are very simple and the catalyst can be recovered without any lost in products formation in the next consecutive cycle.
