A polyoxometalate-based metal–organic complex with the ability to treat pollutants in water was obtained under hydrothermal conditions, namely [Ni(H2L)(HL)2](PMo12O40)·3H3O·4H2O (1) (H2L = 4,4′-(1H,1′H-[2,2′-biimidazole]-1,1′-diyl)dibenzoicacid). Structural analysis reveals that [Ni(H2L)(HL)2] units are interconnected into a 2D layer via hydrogen bonds between adjacent carboxyl groups and molecules of crystallization. [PMo12O40]3− anions embedded within larger pores connected layers through bonds, ultimately expanding structure 3D supramolecular architecture. The intermolecular interactions were studied Hirshfeld surface (HS) analysis. Electrochemical performance tests reveal 1 exhibits electrocatalytic activity toward oxidation reduction diverse water, including NO2−, Cr(VI), BrO3−, Fe(III), ascorbic acid (AA). Additionally, it can also serve as an amperometric sensor for detection BrO3− Cr(VI). Photocatalytic studies compound functions bifunctional photocatalyst, which not only achieves efficient degradation organic dyes but demonstrates remarkable efficiency toxic Compound significant potential practical remediation applications.
