Description
Summary:The title structure, [Zn(SeO4)(CH4N2S)3], is isomorphous with sulfatotris(thiourea)zinc(II). In both structures, the Zn2+ cation is coordinated in a tetrahedral geometry. The corresponding intramolecular distances are quite similar except for the Se—O and S—O distances. Although the hydrogen-bonding patterns are similar, there are some differences; in the title structure all the H atoms are involved in the hydrogen-bond pattern, in contrast to the situation in sulfatotris(thiourea)zinc(II). No reproducible anomalies were detected by differential scanning calorimetry in the range 93–463 K until decomposition started at the higher temperature.
