Abstract
New hybrid arsenotungstates based on Dawson polyanions [C4H7N2]6[As2W18O62]·4H2O (1) have been isolated by conventional solution method and characterized by single-crystal X-ray diffraction, infrared spectrum and UV–visible spectroscopies and thermogravimetric analysis. Hirshfeld surface analysis was performed to study the intermolecular interactions. Compound 1 crystallizes in hexagonal system, in a P-3 space group, with cell parameters a = 20.2904(2) A, b = 20.2904(2) A, c = 16.8246(2) A, and a V = 5998.38(11) A3. Compound 1 exhibits a three-dimensional chain constructed from Well–Dawson anions linked together with (C4H7N2)+ cations and water molecules.
