The material structure described by LiMn(SiO3)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a see-saw-like geometry to one O(1), one O(2), one O(5), and one O(6) atom. Mn(1) is bonded in a see-saw-like geometry to one O(1), one O(2), one O(5), and one O(6) atom. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form corner-sharing SiO4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one Mn(1), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one Mn(1), and one Si(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Si(1) and one Si(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Si(1) and one Si(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Mn(1), and one Si(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Li(1), one Mn(1), and one Si(2) atom. is represented by the CIF file [CIF]
