Li2Cr2SnO6 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. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 octahedra that share edges with three equivalent Cr(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 Cr(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Cr(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Cr(1), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing OLi2Cr2Sn trigonal bipyramids.
Li2Cr2SnO6 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. There are two shorter (2.05 Å) and two longer (2.12 Å) Li(1)-O(2) bond lengths. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 octahedra that share edges with three equivalent Cr(1)O6 octahedra and edges with three equivalent Sn(1)O6 octahedra. Both Cr(1)-O(1) bond lengths are 2.01 Å. There are two shorter (2.04 Å) and two longer (2.07 Å) Cr(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 Cr(1)O6 octahedra. Both Sn(1)-O(1) bond lengths are 2.05 Å. All Sn(1)-O(2) bond lengths are 2.15 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Cr(1) and one Sn(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Cr(1), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing OLi2Cr2Sn trigonal bipyramids.
