The material structure described by Li2Mn(SiO3)2 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with three equivalent Mn(1)O4 tetrahedra, and corners with five equivalent Si(1)O4 tetrahedra. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra and corners with six equivalent Li(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SiO4 tetrahedra that share corners with two equivalent Mn(1)O4 tetrahedra, corners with two equivalent Si(1)O4 tetrahedra, and corners with five equivalent Li(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one 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 corner-sharing OLi2MnSi tetrahedra. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
