Li2Mn2SbO6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded to four equivalent O(1) atoms to form distorted LiO4 trigonal pyramids that share corners with four equivalent Mn(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 24-71°. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) 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, edges with three equivalent Sb(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with eight equivalent Li(1)O4 trigonal pyramids and edges with six equivalent Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), two equivalent Mn(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OLi2Mn2Sb square pyramids. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to two equivalent Mn(1) and one Sb(1) atom.

The corner-sharing octahedral tilt angles range from 24-71°. There are two shorter (2.06 Å) and two longer (2.18 Å) Li(1)-O(1) bond lengths. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) 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, edges with three equivalent Sb(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. Both Mn(1)-O(2) bond lengths are 2.04 Å. There are two shorter (2.04 Å) and two longer (2.41 Å) Mn(1)-O(1) bond lengths. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with eight equivalent Li(1)O4 trigonal pyramids and edges with six equivalent Mn(1)O6 octahedra. Both Sb(1)-O(2) bond lengths are 2.00 Å. All Sb(1)-O(1) bond lengths are 2.05 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), two equivalent Mn(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OLi2Mn2Sb square pyramids.
