The structure described by Li2Mn3SbO8 is Hausmannite-derived structured and crystallizes in the trigonal P31c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(3) and three equivalent O(2) atoms to form LiO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra and corners with nine equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-70°. In the second Li site, Li(2) is bonded to one O(4) and three equivalent O(1) atoms to form distorted LiO4 tetrahedra that share corners with three equivalent Mn(1)O6 octahedra, corners with three equivalent Sb(1)O6 octahedra, and edges with three equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 62-65°. Mn(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form MnO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra,  a cornercorner with one Li(2)O4 tetrahedra, corners with three equivalent Li(1)O4 tetrahedra,  an edgeedge with one Sb(1)O6 octahedra, edges with four equivalent Mn(1)O6 octahedra, and  an edgeedge with one Li(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 44-56°. Sb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, corners with three equivalent Li(1)O4 tetrahedra, corners with three equivalent Li(2)O4 tetrahedra, and edges with three equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-56°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Li(2), two equivalent Mn(1), and one Sb(1) atom. In the second O site, O(2) is bonded to one Li(1), two equivalent Mn(1), and one Sb(1) atom to form distorted OLiMn2Sb trigonal pyramids that share  a cornercorner with one O(3)LiMn3 tetrahedra, corners with two equivalent O(4)LiMn3 tetrahedra, corners with two equivalent O(2)LiMn2Sb trigonal pyramids,  an edgeedge with one O(3)LiMn3 tetrahedra, and edges with two equivalent O(2)LiMn2Sb trigonal pyramids. In the third O site, O(3) is bonded to one Li(1) and three equivalent Mn(1) atoms to form OLiMn3 tetrahedra that share corners with three equivalent O(4)LiMn3 tetrahedra, corners with three equivalent O(2)LiMn2Sb trigonal pyramids, and edges with three equivalent O(2)LiMn2Sb trigonal pyramids. In the fourth O site, O(4) is bonded to one Li(2) and three equivalent Mn(1) atoms to form OLiMn3 tetrahedra that share corners with three equivalent O(3)LiMn3 tetrahedra and corners with six equivalent O(2)LiMn2Sb trigonal pyramids. is represented by the CIF file [CIF]
