Abstract

•A novel compound obtained by dissolution of V2O5 in the chloride–urea mixture•Slow reaction between V2O5 and ChCl–urea•Solubility of V2O5 in the mixture is the result of forming very stable [H2V10O28]4 − complex anion.

The previously reported high solubility data for V2O5 in the deep eutectic solvent of choline chloride and urea (ChCl–urea) is the result of forming [H2V10O28]4 − complex anion.Storing this as-prepared solution for about three months at 20 °C, a new compound, [(CH3)3N(CH2)2OH]4[H2V10O28]·2(NH2)2CO (1), was obtained. The solid-state structure is assembled of dihydrogendecavanadate(V) anions, choline cations and molecules of urea. The crystal structure is further stabilized by electrostatic interactions and by O–H⋯O and N–H⋯O hydrogen bonds. The 51V NMR spectroscopy detected the decavanadate anion in the as-prepared solution.
