Materials Data on LiCr3P3O13 by Materials Project
LiCr3P3O13 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form LiO5 square pyramids that share corners with five CrO6 octahedra, corners with three equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–61°. There are a spread of Li–O bond distances ranging from 1.96–2.38 Å. There are three inequivalent Cr+3.33+ sites. In the first Cr+3.33+ site, Cr+3.33+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent CrO6 octahedra, a cornercorner with one CrO5 square pyramid, corners with three equivalent LiO5 square pyramids, corners with three PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Cr–O bond distances ranging from 1.87–2.10 Å. In the second Cr+3.33+ site, Cr+3.33+ is bonded to five O2- atoms to form CrO5 square pyramids that share a cornercorner with one CrO6 octahedra and corners with five PO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Cr–O bond distances ranging from 1.91–2.01 Å. In the third Cr+3.33+ site, Cr+3.33+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent CrO6 octahedra, corners with two equivalent LiO5 square pyramids, corners with four PO4 tetrahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Cr–O bond distances ranging from 2.00–2.06 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 CrO6 octahedra and corners with three equivalent CrO5 square pyramids. The corner-sharing octahedral tilt angles are 29°. There is three shorter (1.54 Å) and one longer (1.55 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four CrO6 octahedra, a cornercorner with one CrO5 square pyramid, and an edgeedge with one LiO5 square pyramid. The corner-sharing octahedra tilt angles range from 43–55°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CrO6 octahedra, a cornercorner with one CrO5 square pyramid, corners with three equivalent LiO5 square pyramids, and an edgeedge with one CrO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cr+3.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Cr+3.33+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cr+3.33+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cr+3.33+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three Cr+3.33+ atoms. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr+3.33+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cr+3.33+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cr+3.33+, and one P5+ atom.
