Materials Data on Li2ZrFe(PO4)3 by Materials Project

Li2FeZr(PO4)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.84–2.07 Å. In the second Li1+ site, Li1+ is bonded in a distorted trigonal planar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.92–2.14 Å. Zr4+ is bonded to five O2- atoms to form distorted ZrO5 trigonal bipyramids that share a cornercorner with one FeO4 tetrahedra, corners with two PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Zr–O bond distances ranging from 1.93–2.29 Å. Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with three PO4 tetrahedra and a cornercorner with one ZrO5 trigonal bipyramid. There are a spread of Fe–O bond distances ranging from 1.88–1.98 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one FeO4 tetrahedra, a cornercorner with one PO4 tetrahedra, and a cornercorner with one ZrO5 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra, a cornercorner with one ZrO5 trigonal bipyramid, and an edgeedge with one ZrO5 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.52–1.58 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent FeO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Zr4+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one P5+ atom. In the third O2- site, O2- is bonded in an L-shaped geometry to one Zr4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Fe3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Zr4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Zr4+, and one Fe3+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe3+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Zr4+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one P5+ atom.
