Abstract:
The title compound, (C3H12N2)[Zn3(SeO3)4].2H2O, is built up from organic cations, {[Zn3(SeO3)4]2-}n macroanionic sheets and water molecules. The inorganic component of the structure is notable for incorporating both octahedrally and tetrahedrally coordinated Zn atoms. A network of N-H...O and O-H...O hydrogen bonds helps to establish the layered structure. The six-coordinate Zn atom has site symmetry 1, and one C and the two water O atoms have site symmetry m.
