Interactions between diperoxovanadate complex and amide ligands in aqueous solution.

Multinuclear ((1)H, (13)C, (14)N, and (51)V) NMR spectroscopy has been used to study the reactions between the diperoxovanadate complex K(3)[OV(O(2))(2)(C(2)O(4))] x H(2)O (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.
