| Abstract: | The reaction system of diperoxooxalatovanadate {K3[VO(O2)2‐(C2O4)]·H2O, bpV(Oxa)} and imidazole was studied in an aqueous solution by ID multinuclear (1H, 13C and 51V) NMR, 2D NMR diffusion ordered spectroscopy (DOSY), and variable temperature NMR techniques. It was shown that DOSY was a useful tool for the study of a mixture. All of the 1H and 13C NMR signals of the peroxovanadate (V) complexes were assigned. The NMR experimental results indicated that a new complex was formed through the coordination interactions between bpV(Oxa) and imidazole. The newly‐formed complex is stable under the experimental condition. Electrospray ionization mass spectrometry (ESI‐MS) provides positive evidence to support the conclusion. |
