Materials Data on Mn(SbO3)2 by Materials Project

Abstract

MnSb2O6 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with eight equivalent SbO6 octahedra and edges with two equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Mn–O bond distances ranging from 2.13–2.16 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with four equivalent MnO6 octahedra, corners with four equivalent SbO6 octahedra, an edgeedge with one MnO6 octahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedra tilt angles range from 45–53°. There are a spread of Sb–O bond distances ranging from 2.02–2.04 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Mn2+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn2+ and two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn2+ and two equivalent Sb5+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Mn2+ and two equivalent Sb5+ atoms.
