Title: Materials Data on Li4CuSi2O7 by Materials Project

Abstract

Li4CuSi2O7 is Stannite-like structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner with one CuO4 tetrahedra, corners with five SiO4 tetrahedra, and corners with six LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.16 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 SiO4 tetrahedra, and corners with six LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.01 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent CuO4 tetrahedra, corners with four SiO4 tetrahedra, and corners with five LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.98–2.11 Å. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent CuO4 tetrahedra, corners with five LiO4 tetrahedra, and corners with five SiO4 tetrahedra. There aremore » a spread of Li–O bond distances ranging from 1.94–2.18 Å. Cu2+ is bonded to four O2- atoms to form CuO4 tetrahedra that share corners with four SiO4 tetrahedra and corners with eight LiO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.96–1.99 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one CuO4 tetrahedra, a cornercorner with one SiO4 tetrahedra, and corners with ten LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.73 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra, corners with three equivalent CuO4 tetrahedra, and corners with eight LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.70 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and one Si4+ atom to form distorted corner-sharing OLi3Si tetrahedra. In the second O2- site, O2- is bonded to two Li1+, one Cu2+, and one Si4+ atom to form distorted corner-sharing OLi2CuSi tetrahedra. In the third O2- site, O2- is bonded to two Li1+, one Cu2+, and one Si4+ atom to form distorted corner-sharing OLi2CuSi tetrahedra. In the fourth O2- site, O2- is bonded to two Li1+, one Cu2+, and one Si4+ atom to form corner-sharing OLi2CuSi tetrahedra. In the fifth O2- site, O2- is bonded to two Li1+, one Cu2+, and one Si4+ atom to form corner-sharing OLi2CuSi tetrahedra. In the sixth O2- site, O2- is bonded to two Li1+ and two Si4+ atoms to form corner-sharing OLi2Si2 tetrahedra. In the seventh O2- site, O2- is bonded to three Li1+ and one Si4+ atom to form corner-sharing OLi3Si tetrahedra.« less
