Title: Materials Data on Mg2BiPO6 by Materials Project

Abstract

BiMg2PO6 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to five O2- atoms to form distorted MgO5 trigonal bipyramids that share corners with three equivalent PO4 tetrahedra, corners with two equivalent MgO5 trigonal bipyramids, and an edgeedge with one MgO5 trigonal bipyramid. There are a spread of Mg–O bond distances ranging from 1.97–2.09 Å. In the second Mg2+ site, Mg2+ is bonded to five O2- atoms to form distorted MgO5 trigonal bipyramids that share corners with three equivalent PO4 tetrahedra, corners with two equivalent MgO5 trigonal bipyramids, and an edgeedge with one MgO5 trigonal bipyramid. There are a spread of Mg–O bond distances ranging from 1.99–2.10 Å. Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.22 Å) and two longer (2.25 Å) Bi–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six MgO5 trigonal bipyramids. There is two shorter (1.54 Å) and two longer (1.57 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two Mg2+more » and two equivalent Bi3+ atoms to form a mixture of corner and edge-sharing OMg2Bi2 tetrahedra. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mg2+ and one P5+ atom. In the third O2- site, O2- is bonded in a linear geometry to one Mg2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one P5+ atom.« less
