Li2MnSiO4 is Stannite-like structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra, corners with four equivalent MnO4 tetrahedra, and corners with four equivalent SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.06 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra, corners with four equivalent MnO4 tetrahedra, and corners with four equivalent SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.00–2.09 Å. Mn2+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra and corners with eight LiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.06–2.10 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent MnO4 tetrahedra and corners with eight LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.65–1.67 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two Li1+, one Mn2+, and one Si4+ atom to form corner-sharing OLi2MnSi tetrahedra. In the second O2- site, O2- is bonded to two Li1+, one Mn2+, and one Si4+ atom to form corner-sharing OLi2MnSi tetrahedra. In the third O2- site, O2- is bonded to two Li1+, one Mn2+, and one Si4+ atom to form distorted corner-sharing OLi2MnSi tetrahedra. In the fourth O2- site, O2- is bonded to two Li1+, one Mn2+, and one Si4+ atom to form corner-sharing OLi2MnSi tetrahedra.
