Title: Synthesis, structure refinement at 296 K and physico-chemical characterizations of KMnHP{sub 3}O{sub 10}

Abstract

Potassium manganese(III) monohydrogentriphosphate KMnHP{sub 3}O{sub 10} was synthesized by flux method and characterized by single-crystal X-ray diffraction, crystallizes in the monoclinic system with centric space group C2/c. The parameters of the unit cell are a = 12.104(1), b = 8.287(1). c = 9.150(1) A, {beta} = 110.97(1) deg. and Z = 4. The structure was solved at 296 K using 893 independent reflections and refined until R(F) = 0.022; wR(F{sup 2}) = 0.045. The atomic arrangement of the title compound consists of MnO{sub 6} octahedra linked by hydrogentriphosphate anions to form a three-dimensional framework containing tunnels parallel to the c-axis where the K{sup +} cations are inserted. The structure of KMnHP{sub 3}O{sub 10} contains a single Mn site which is surrounded by typical Jahn-Teller [2 + 2 + 2] distorted octahedron. The title material has been also characterized by different physico-chemical techniques: powder X-ray diffraction, IR, NMR and CI spectroscopies and DTA-TGA-DSC thermal analysis.
