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°.

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. There is one shorter (2.88 Å) and two longer (3.15 Å) Ce(1)-Ce(1,1) bond lengths. There are four shorter (2.93 Å) and two longer (2.94 Å) Ce(1)-Cu(1) bond lengths. Both Ce(1)-In(1) bond lengths are 3.33 Å. 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. Both Ce(1)-Ce(1) bond lengths are 3.15 Å. There are four shorter (2.93 Å) and two longer (2.94 Å) Ce(1)-Cu(1) bond lengths. Both Ce(1)-In(1) bond lengths are 3.33 Å.
