The material structure described by Li2MnSiO4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Li(1) is bonded to four equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Mn(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. Mn(1) is bonded to four equivalent O(1) atoms to form distorted MnO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Mn(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. O(1) is bonded to two equivalent Li(1), one Mn(1), and one Si(1) atom to form corner-sharing OLi2MnSi tetrahedra. is represented by the CIF card [CIF]
