The material structure described by Li2Mn3SbO8 is Spinel-derived structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form LiO4 tetrahedra that share corners with three equivalent Mn(2)O6 octahedra, corners with three equivalent Sb(1)O6 octahedra, and corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-63°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with two equivalent Sb(1)O6 octahedra. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. Sb(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Mn(2), and two equivalent Mn(1) atoms to form OLiMn3 tetrahedra that share corners with three equivalent O(1)LiMn3 tetrahedra, corners with six equivalent O(3)LiMn2Sb trigonal pyramids, and edges with two equivalent O(3)LiMn2Sb trigonal pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Mn(1), and one Sb(1) atom. In the third O site, O(3) is bonded to one Li(1), one Mn(1), one Mn(2), and one Sb(1) atom to form distorted OLiMn2Sb trigonal pyramids that share corners with three equivalent O(1)LiMn3 tetrahedra, corners with six equivalent O(3)LiMn2Sb trigonal pyramids,  an edgeedge with one O(1)LiMn3 tetrahedra, and  an edgeedge with one O(3)LiMn2Sb trigonal pyramid. is represented by the CIF card [CIF]
