Materials Data on MnPO4 by Materials Project

Abstract

MnPO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mn3+ is bonded to five O2- atoms to form MnO5 trigonal bipyramids that share corners with five equivalent PO4 tetrahedra and an edgeedge with one MnO5 trigonal bipyramid. There are a spread of Mn–O bond distances ranging from 1.90–2.16 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with five equivalent MnO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn3+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mn3+ and one P5+ atom.
