Li(SiO2)6 crystallizes in the monoclinic C2 space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. There are four inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(2), one O(3), and two equivalent O(5) atoms to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(1), one O(6), and two equivalent O(4) atoms to form corner-sharing SiO4 tetrahedra. In the third Si site, Si(3) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form corner-sharing SiO4 tetrahedra. In the fourth Si site, Si(4) is bonded to two equivalent O(2) and two equivalent O(6) atoms to form corner-sharing SiO4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one Si(2), and one Si(3) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Si(1) and one Si(4) 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(3) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Si(2) atoms. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Si(2) and one Si(4) atom.
