The structure described by Li2Mn2SbO6 crystallizes in the orthorhombic C222_1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form distorted LiO4 trigonal pyramids that share corners with four equivalent Mn(2)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 23-72°. In the second Li site, Li(2) is bonded in a distorted see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. 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 distorted MnO6 octahedra that share edges with three equivalent Mn(2)O6 octahedra, edges with three equivalent Sb(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MnO6 octahedra that share corners with four equivalent Li(1)O4 trigonal pyramids, edges with three equivalent Mn(1)O6 octahedra, and edges with three equivalent Sb(1)O6 octahedra. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with four equivalent Li(1)O4 trigonal pyramids, edges with three equivalent Mn(1)O6 octahedra, and edges with three equivalent Mn(2)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Mn(1), one Mn(2), and one Sb(1) atom. In the second O site, O(2) is bonded to one Li(1), one Li(2), one Mn(1), one Mn(2), and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OLi2Mn2Sb trigonal bipyramids. In the third O site, O(3) is bonded to one Li(1), one Li(2), one Mn(1), one Mn(2), and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OLi2Mn2Sb square pyramids. is represented by the CIF card [CIF]
