The material structure described by Li2Mn5O10 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(5) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 12°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 12-13°. In the third Mn site, Mn(3) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 13°. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Mn(1), one Mn(2), and two equivalent Mn(3) atoms to form a mixture of corner and edge-sharing OLiMn4 square pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1) and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a see-saw-like geometry to one Mn(1), one Mn(2), and two equivalent Mn(3) atoms. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Mn(1), one Mn(2), and one Mn(3) atom. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1), one Mn(1), and one Mn(3) atom. is represented by the CIF file [CIF]
