Title: Materials Data on LiCoP2O7 by Materials Project

Abstract

LiCoP2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 pentagonal pyramids that share corners with three equivalent CoO6 octahedra, corners with five PO4 tetrahedra, an edgeedge with one CoO6 octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 54–69°. There are a spread of Li–O bond distances ranging from 2.10–2.69 Å. Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three equivalent LiO6 pentagonal pyramids, corners with six PO4 tetrahedra, and an edgeedge with one LiO6 pentagonal pyramid. There are a spread of Co–O bond distances ranging from 1.94–2.09 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 CoO6 octahedra, corners with two equivalent LiO6 pentagonal pyramids, a cornercorner with one PO4 tetrahedra, and an edgeedge with one LiO6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 39–57°. There are a spread of P–O bond distances ranging from 1.53–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms tomore » form PO4 tetrahedra that share corners with three equivalent CoO6 octahedra, corners with three equivalent LiO6 pentagonal pyramids, and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 25–56°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Co3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Co3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Co3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two P5+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Co3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Co3+, and one P5+ atom.« less
