Abstract

A new Zr-substituted sandwich-type polyoxometalate, H₈K₃[Zr₃K₂(μ₃-O)₂(μ₂-OH)(H₂O)₂(A-α-PW₉O₃₄)₂]·2Cl⁻·7H₂O (1), has been made under hydrothermal conditions. 1 was characterized by IR spectrum, thermogravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction, respectively. Crystal data for 1: tetragonal space group P4₂2₁2, a = 24.0096(3), b = 24.0096(3), c = 14.7416(3) Å, V = 8498.0(2) Å³ and Z = 4. Single crystal X-ray structure analysis reveals that 1 exhibits a three-dimensional framework structure based on Zr₃K₂-substituted sandwich-type polyanions [Zr₃K₂(μ₃-O)₂(μ₂-OH)(H₂O)₂(PW₉O₃₄)₂]⁹⁻ linked by K–O chains. UV–Vis spectrum indicates that 1 is a wide-gap semiconductor. In addition, the SHG of 1 was also investigated.
