Synthesis, structure and magnetic behavior of a new three-dimensional Manganese phosphite-oxalate: [C2N2H10][Mn2II(OH2)2(HPO3)2(C2O4)]

A novel manganese phosphite-oxalate, [C2N2H10][Mn2II(OH2)2(HPO3)2(C2O4)] has been hydothermally synthesized and its structure determined by single-crystal X-ray diffraction. The structure consists of neutral manganese phosphite layers, [Mn(HPO3)]∞, formed by MnO6 octahedra and HPO3 units, cross-linked by the oxalate moieties. The organic cations occupy the middle of the 8-membered one-dimensional channels. Magnetic studies indicate weak antiferromagnetic interactions between the Mn2+ ions.

A new antiferromagnetic three-dimensional inorganic–organic hybrid compound, [C2N2H10][Mn2II(OH2)2(HPO3)2(C2O4)] has been prepared hydrothermally. The compound has neutral manganese layers pillared by oxalate units. The neutral manganese layers are shown here.Figure optionsDownload full-size imageDownload as PowerPoint slide
