Title: Materials Data on Li2CuAsO4 by Materials Project

Abstract

Li2CuAsO4 crystallizes in the monoclinic P2_1/c 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 LiO4 tetrahedra and corners with four equivalent AsO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.99–2.07 Å. In the second Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.97–2.47 Å. Cu1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.91–2.55 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra. There are a spread of As–O bond distances ranging from 1.71–1.75 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and one As5+ atom to form distorted OLi3As tetrahedra that share corners with two equivalent OLi3As tetrahedra, corners with two equivalent OLi2CuAs trigonal pyramids, and an edgeedge with one OLi2CuAs trigonal pyramid. In the second O2- site, O2- ismore » bonded to two Li1+, one Cu1+, and one As5+ atom to form a mixture of distorted edge and corner-sharing OLi2CuAs trigonal pyramids. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu1+, and one As5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Li1+, two equivalent Cu1+, and one As5+ atom.« less
