Title: Materials Data on Li2Cu2Si4O11 by Materials Project

Abstract

Li2Cu2Si4O11 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 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.64 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.23 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six SiO4 tetrahedra and an edgeedge with one CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.60 Å. In the second Cu2+ site, Cu2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.96–2.72 Å. There are four 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 CuO6 octahedra and corners with two SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 7°. There are a spread of Si–Omore » bond distances ranging from 1.59–1.68 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 61–68°. There are a spread of Si–O bond distances ranging from 1.62–1.65 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one CuO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 61°. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the fourth Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with two SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–70°. There are a spread of Si–O bond distances ranging from 1.61–1.69 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+, one Cu2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Si4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two Li1+, one Cu2+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+ and two Si4+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two Si4+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two Si4+ atoms. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cu2+, and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Cu2+ and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cu2+, and one Si4+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two Si4+ atoms. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to three Cu2+ and one Si4+ atom.« less
