The material structure described by Ce2Ni2Sn crystallizes in the orthorhombic Immm space group. Ce(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Ce(1) and four equivalent Ni(1) atoms to form a mixture of face and edge-sharing SnCe8Ni4 cuboctahedra. is represented by the CIF card [CIF]
