Title: Materials Data on Li2CoP2O7 by Materials Project

Abstract

Li2CoP2O7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.17 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with two equivalent CoO5 square pyramids, corners with four PO4 tetrahedra, an edgeedge with one CoO5 square pyramid, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.92–2.06 Å. Co2+ is bonded to five O2- atoms to form CoO5 square pyramids that share corners with two equivalent LiO4 tetrahedra, corners with five PO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Co–O bond distances ranging from 2.05–2.15 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 CoO5 square pyramids, a cornercorner with one LiO4 tetrahedra, and a cornercorner with one PO4 tetrahedra. There are a spread of P–O bond distancesmore » ranging from 1.53–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CoO5 square pyramids, a cornercorner with one PO4 tetrahedra, and corners with three equivalent LiO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.51–1.63 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Co2+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co2+, and one P5+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Co2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Co2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one P5+ atom. In the seventh O2- site, O2- is bonded to two equivalent Li1+, one Co2+, and one P5+ atom to form distorted edge-sharing OLi2CoP trigonal pyramids.« less
