Title: Materials Data on Li3Cr2P2(CO7)2 by Materials Project

Abstract

Li3Cr2P2(CO7)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with two CrO6 octahedra, corners with three PO4 tetrahedra, and an edgeedge with one CrO6 octahedra. The corner-sharing octahedra tilt angles range from 65–76°. There are a spread of Li–O bond distances ranging from 1.93–2.36 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with two CrO6 octahedra, corners with three PO4 tetrahedra, and an edgeedge with one CrO6 octahedra. The corner-sharing octahedra tilt angles range from 64–73°. There are a spread of Li–O bond distances ranging from 1.98–2.22 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.97–2.23 Å. There are two inequivalent Cr+3.50+ sites. In the first Cr+3.50+ site, Cr+3.50+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with four PO4 tetrahedra, corners with two LiO5 trigonal bipyramids, and an edgeedge with onemore » LiO5 trigonal bipyramid.

In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+ and one C4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one C4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one Cr+3.50+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr+3.50+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two Li1+, one Cr+3.50+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.50+, and one C4+ atom. In the thirteenth O2- site, O2- is bonded in an L-shaped geometry to one Cr+3.50+ and one C4+ atom. In the fourteenth O2- site, O2- is bonded in a trigonal non-coplanar geometry to two Li1+ and one C4+ atom.« less
