The structure described by Ce2Cu2In crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 11-coordinate geometry to three Ce(1,1); six equivalent Cu(1); and two equivalent In(1) atoms. In the second Ce site, Ce(1) is bonded in a 11-coordinate geometry to three Ce(1,1); six equivalent Cu(1); and two equivalent In(1) atoms. Cu(1) is bonded in a 6-coordinate geometry to six Ce(1,1) atoms. In(1) is bonded to four Ce(1,1) and two equivalent In(1) atoms to form distorted corner-sharing InCe4In2 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. is represented by the CIF card [CIF]
