Abstract:

Two open-framework manganese phosphites, (NH4)2Mn3(HPO3)4(1) and Mn(HPO3)(2), were synthesized under ionothermal conditions and characterized by single crystal X-ray diffraction. The two compounds were synthesized under the same conditions, but the structures were different with the use of diffe-rent ionic liquids. The framework structure of compound 1 is built up from MnO6 octahedra and phosphite groups, giving rise to a two-dimensional framework with NH4+ cations filling between the layers; the structure of compound 2 consists of a 3D condensed framework of edge-sharing MnO6 octahedra linking to [HPO3] units via oxygens. The compounds were further characterized by scanning electron microscopy(SEM), powder X-ray diffraction(PXRD) and inductively coupled plasma(ICP), and the magnetic measurements results reveal that strong antiferromagnetic interaction exists in compound 1.
