The crystal structure described by Li2Ni2SnO6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. Ni(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NiO6 octahedra that share edges with three equivalent Ni(1)O6 octahedra and edges with three equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SnO6 octahedra that share edges with six equivalent Ni(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 Ni(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLi2Ni2Sn square pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ni(1) and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
