| Abstract: | A polyoxometalate‐based supramolecular assembly with the formula (Hcpy)6H2PMo12O40] ( 1 ) cpy = 4‐(5‐chloropyridin‐2‐yl)pyridine] was prepared and characterized. Noncovalent intermolecular interactions including hydrogen bonds (N–H ··· O–Mo, N–H ··· H–N, and C–H ··· O–Mo), halogen (C–Cl ··· O–Mo), and face‐to‐face π packing coexist in crystal 1 , which serves the insolubility of 1 in aqueous solution. Compound 1 was used as a solid material to fabricate a bulk‐modified carbon paste electrode by direct mixing. Electrochemistry results indicated that 1 is possessed of electrocatalytic activities toward the reduction reactions of chlorate, hydrogen peroxide, and nitrite. |
