The compound described by Li(SiO2)5 crystallizes in the orthorhombic Pmm2 space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(1), one O(4), and two equivalent O(3) atoms to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(2), one O(5), and two equivalent O(3) atoms to form distorted corner-sharing SiO4 tetrahedra. In the third Si site, Si(3) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing SiO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Si(1) and one Si(3) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one Si(2), and one Si(3) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Li(1), one Si(1), and one Si(2) atom. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent Si(1) atoms. In the fifth O site, O(5) is bonded in a linear geometry to two equivalent Si(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
