An organic-inorganic mercury coordination compound [Hg(DMSO)2(H2O)]2 [GeW12O40]·DMSO·H2O(DMSO =dimethyl sulfoxide) has been synthesized and characterized by IR, UV spectra, elemental analysis, TG-DTA and X-ray single-crystal diffraction. Structural analysis revealed that in the title compound, the mercury is three-coordinated to show the distorted trigonal cone geometry, and depending on the electrostatic interaction to connect the polyanion [α-GeW12O40]4-. TG-DTA study manifests the decomposition temperature of the polyanion framework in the title compound is 513.5℃, which is much higher than that of the anion framework. It means that the formation of the organic-inorganic mercury coordination compound made the polyanion [α-GeW12O40]4- to be more stable.
