【 摘 要 】

A new isopolyoxovanadate compound [Zn(phen)₃]₂·(V₄O₁₂)·phen·20H₂O (phen = 1,10-phenathroline) (1) has been synthesized in aqueous solution and characterized using IR and UV/Vis spectroscopy, elemental analysis, thermal gravimetric analysis, powder, single-crystal X-ray diffractions, and field emission scanning electron microscopy. The molecular structure of 1 exists as two kinds of [V₄O₁₂]⁴⁻ polyoxoanions: distorted chair-like and coplanar conformations, two independent [Zn(phen)₃]²⁺ units and free phen. In the solid state, compound 1 forms a stable three-dimensional supramolecular structure through electrostatic interactions, π–π stacking interactions and multiform hydrogen bonds. The electrocatalytic activity and determination of DA of compound 1 have been studied by cyclic voltammetry and differential pulse voltammetry, respectively.
