Li2Mn2SnO6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded to four equivalent O(2) atoms to form distorted LiO4 trigonal pyramids that share corners with four equivalent Mn(1)O6 octahedra, corners with four equivalent Sn(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 20-69°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) 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 Sn(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 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 in a distorted trigonal non-coplanar geometry to two equivalent Mn(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Mn(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLi2Mn2Sn trigonal bipyramids.

The corner-sharing octahedral tilt angles range from 20-69°. There are two shorter (2.03 Å) and two longer (2.16 Å) Li(1)-O(2) bond lengths. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) 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 Sn(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. Both Mn(1)-O(1) bond lengths are 1.96 Å. There are two shorter (1.96 Å) and two longer (2.38 Å) Mn(1)-O(2) bond lengths. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with eight equivalent Li(1)O4 trigonal pyramids and edges with six equivalent Mn(1)O6 octahedra. Both Sn(1)-O(1) bond lengths are 2.12 Å. All Sn(1)-O(2) bond lengths are 2.11 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mn(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Mn(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLi2Mn2Sn trigonal bipyramids.
