Materials Data on Li2Cr3P4(HO4)4 by Materials Project
Li2Cr3P4(HO4)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.09 Å. There are two inequivalent Cr2+ sites. In the first Cr2+ site, Cr2+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent CrO6 octahedra. There are a spread of Cr–O bond distances ranging from 2.07–2.49 Å. In the second Cr2+ site, Cr2+ is bonded to six O2- atoms to form distorted CrO6 octahedra that share corners with five PO4 tetrahedra and edges with two CrO6 octahedra. There are a spread of Cr–O bond distances ranging from 2.05–2.67 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 CrO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–74°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with five CrO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 38–61°. There are a spread of P–O bond distances ranging from 1.51–1.64 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Cr2+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cr2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Cr2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cr2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two Cr2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Cr2+ and one P5+ atom.
