Materials Data on LiCuSi2O5 by Materials Project
LiCuSi2O5 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with six SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.02–2.21 Å. Cu1+ is bonded in a 2-coordinate geometry to two O2- atoms. There is one shorter (1.92 Å) and one longer (1.93 Å) Cu–O bond length. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three SiO4 tetrahedra and corners with four equivalent LiO4 tetrahedra. There is one shorter (1.61 Å) and three longer (1.66 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and corners with three SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.69 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu1+, and one Si4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu1+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Si4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and two equivalent Si4+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Si4+ atoms.
