Sandwich-type tungstoantimonate was synthesized via aqueous solution synthesis. We structurally characterized the compound using elemental analysis, infrared spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The results suggested that the compound is a triclinic system with a P-1 space group. The two-dimensional layered structure was formed through covalent bonding interactions between the sandwich-type polyoxoanion and the Mn2+ cations.
