The compound described by Li2MnSiO4 crystallizes in the trigonal P3_121 space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. Mn(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Si(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with eight equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Mn(1), and one Si(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), one Mn(1), and one Si(1) atom to form distorted corner-sharing OLi2MnSi trigonal pyramids. is represented by the CIF card [CIF]
