The corresponding peroxovanadate species abbreviate bpv(oxa), bpv(pic), bpv(bipy), and bpv(phen)] and 1-methylimidazole (abbr. ) in solution were explored using multinuclear ( 1 H, 13 C, and 51 V) magnetic resonance, COSY, and variable temperature NMR in 0.15 mol/l NaCl ionic medium for mimicking the physiological conditions. The experimental results indicated the activity order of these four complexes with 1-methylimidazole as follows: bpv(oxa) bpv(pic) bpv(bipy) bpv(phen). Both the coordinating capability and the steric effect of the organic ligands affect the reaction equilibrium. At the same time, a new six-coordinated peroxovanadate species [OV(O 2 ) 2 ()] is formed due to the competitive coordination.
