Materials Data on SrZr(PO4)2 by Materials Project
SrZr(PO4)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.58–3.09 Å. Zr4+ is bonded to seven O2- atoms to form ZrO7 pentagonal bipyramids that share corners with five PO4 tetrahedra, an edgeedge with one ZrO7 pentagonal bipyramid, and an edgeedge with one PO4 tetrahedra. There are a spread of Zr–O bond distances ranging from 2.05–2.31 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent ZrO7 pentagonal bipyramids. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent ZrO7 pentagonal bipyramids and an edgeedge with one ZrO7 pentagonal bipyramid. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Zr4+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+, one Zr4+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Zr4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Sr2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+, one Zr4+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, one Zr4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Zr4+, and one P5+ atom.
