Title: Materials Data on Li2CuPO4 by Materials Project

Abstract

Li2CuPO4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with two equivalent PO4 tetrahedra, corners with four equivalent LiO4 tetrahedra, corners with four equivalent CuO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.99–2.09 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent CuO4 tetrahedra, corners with four equivalent LiO4 tetrahedra, corners with four equivalent PO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There is two shorter (1.94 Å) and two longer (2.01 Å) Li–O bond length. Cu1+ is bonded to four O2- atoms to form CuO4 tetrahedra that share corners with four equivalent PO4 tetrahedra, corners with six LiO4 tetrahedra, and an edgeedge with one CuO4 tetrahedra. There are two shorter (2.05 Å) and two longer (2.15 Å) Cu–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CuO4 tetrahedra, corners with six LiO4 tetrahedra,more » and an edgeedge with one LiO4 tetrahedra. There is one shorter (1.55 Å) and three longer (1.56 Å) P–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Cu1+, and one P5+ atom. In the second O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted OLi3P tetrahedra that share corners with eight equivalent OLi2CuP trigonal pyramids and an edgeedge with one OLi3P tetrahedra. In the third O2- site, O2- is bonded to two Li1+, one Cu1+, and one P5+ atom to form distorted OLi2CuP trigonal pyramids that share corners with four equivalent OLi3P tetrahedra, corners with two equivalent OLi2CuP trigonal pyramids, and an edgeedge with one OLi2CuP trigonal pyramid.« less
