Materials Data on Li2Mn(SiO3)2 by Materials Project
Abstract
Li2Mn(SiO3)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.24 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.07–2.54 Å. Mn2+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with four SiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.08–2.12 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent MnO4 tetrahedra and corners with two equivalent SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.68 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent MnO4 tetrahedra and corners with two equivalent SiO4 tetrahedra. There is three shorter (1.63 Å) and one longer (1.68 Å) Si–O bond length. There aremore »

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 in a 4-coordinate geometry to two Li1+, one Mn2+, and one Si4+ atom. 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 in a distorted see-saw-like geometry to two Li1+, one Mn2+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two Si4+ atoms. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms.},
