The integrated analytical results show that the novel ligand coexists in ketoform and enolform structures under the measuring conditions, the ketoform structure may change into the enolform structure during the coordination and bonds with the central ion by two O atoms of the enolized hydroxyl group of pyrazolone ring and H2O and the N atom of the imine group and the N atom containing H of benzimidazole ring by losing the proton. And the coordination number of these complexes is four.
