Materials Data on Li2Si2O5 by Materials Project
Li2Si2O5 crystallizes in the orthorhombic Ccc2 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra, corners with five equivalent SiO4 tetrahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.97–2.08 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent SiO4 tetrahedra and corners with five equivalent LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.60–1.67 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Li1+ and one Si4+ atom to form a mixture of distorted edge and corner-sharing OLi3Si tetrahedra. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Li1+ and two equivalent Si4+ atoms.
