Materials Data on Li2Mn2(SiO3)3 by Materials Project
Abstract
Li2Mn2(SiO3)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a distorted bent 120 degrees geometry to two O2- atoms. There is one shorter (1.88 Å) and one longer (1.92 Å) Li–O bond length. Mn2+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with four SiO4 tetrahedra and an edgeedge with one MnO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.04–2.10 Å. There are three 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 SiO4 tetrahedra. There is two shorter (1.63 Å) and two longer (1.66 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two SiO4 tetrahedra and corners with four equivalent MnO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.67 Å. In the third 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 SiO4 tetrahedra. Theremore »

In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one Si4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two Si4+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Si4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mn2+ and one Si4+ atom.
