Abstract
Multinuclear (1H, 13C, 14N, and 51V) NMR spectroscopy has been used to study the reactions between the diperoxovanadate complex K3[OV(O2)2(C2O4)]·H2O (abbr. bpV(ox)) and ethylenediamine or diethylamine in aqueous solution. The interaction between bpV(ox) and diethylamine was very weak and no new complex was formed. However, bpV(ox) reacted with ethylenediamine giving a new product in which ethylenediamine attached to the vanadium atom via one nitrogen atom in a monodentate manner. Diffusion ordered spectroscopy (DOSY) measurements and theoretical calculations proved the formation of new product in bpV(ox) and ethylenediamine. The vanadium atoms in both [OV(O2)2(C2O4)]3− and [OV(O2)2(en)]− species are six coordinated in solution state.
