Synthesis, crystal structure and charge-distribution validation of a new alluaudite-type phosphate, Na_2.22Mn_0.87In_1.68(PO₄)₃.

ABSTRACT: Na_2.22Mn_0.87In_1.68(PO₄₎₃, sodium manganese indium tris-(phosphate) (2.22/0.87/1.68), was obtained in the form of single crystals by a flux method and was structurally characterized by single-crystal X-ray diffraction. The compound belongs to the alluaudite structure type (space group C2/c) with general formula X(2)X(1)M(1)M(2)₂(PO₄)₃. The X(2) and X(1) sites are partially occupied by sodium [occupancy 0.7676 (17) and 1/2] while the M(1) and M(2) sites are fully occupied within a mixed distribution of sodium/manganese(II) and manganese(II)/indium, respectively. The three-dimensional anionic framework is built up on the basis of M(2)_2<
