摘要

In this article, two new tetra-Zr(iv)-substituted sandwich-type Keggin polyoxometalates functionalized by chiral d-tartaric acid and glycolic acid, K ₂ H ₁₀ [Zr ₄ (H ₂ O) ₂ (μ-OH)(μ ₃ -O) ₂ (d-tartH)(GeW ₁₀ O ₃₇ ) ₂ ]·27H ₂ O (1, D-tartH ₄ = d-tartaric acid) and K ₂ H ₁₀ [Zr ₄ (H ₂ O) ₂ (μ ₃ -O) ₂ (gly) ₂ (GeW ₁₀ O ₃₇ ) ₂ ]·32H ₂ O (2, glyH ₂ = glycolic acid), have been synthesized under hydrothermal conditions and characterized by FT-IR spectra, elemental analysis, single-crystal X-ray structure analysis, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), ultraviolet-visible absorption spectroscopy (UV-vis) and cyclic voltammetry (CV). The structure analysis reveals that both 1 and 2 contain a [Zr ₄ (H ₂ O) ₂ (μ ₃ -O) ₂ (GeW ₁₀ O ₃₇ ) ₂ ] cluster. UV-vis spectra indicate that both compounds are a wide-gap semiconductor. In addition, compound 1 is a chiral Zr(iv)-substituted sandwich-type Keggin cluster because the d-tartH ligand is chiral and the Flack divisor of 1 is 0.00, showing non-linear optical properties. The cyclic voltammograms indicate that compounds 1 and 2 have good electrocatalytic activity in the reduction of H ₂ O ₂ .
