Li2Co2SnO6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share edges with three equivalent Co(1)O6 octahedra and edges with three equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share edges with six equivalent Co(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 Co(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Co(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLi2Co2Sn trigonal bipyramids.
Li2Co2SnO6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. All Li(1)-O(2) bond lengths are 2.07 Å. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share edges with three equivalent Co(1)O6 octahedra and edges with three equivalent Sn(1)O6 octahedra. Both Co(1)-O(1) bond lengths are 1.98 Å. There are two shorter (2.02 Å) and two longer (2.13 Å) Co(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 edges with six equivalent Co(1)O6 octahedra. Both Sn(1)-O(1) bond lengths are 2.06 Å. All Sn(1)-O(2) bond lengths are 2.13 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 Co(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Co(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLi2Co2Sn trigonal bipyramids.
