The material described by Ce2(CoCu)5 crystallizes in the orthorhombic Pmmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 18-coordinate geometry to two equivalent Co(1), four equivalent Co(2), four equivalent Cu(1), and eight equivalent Cu(2) atoms. In the second Ce site, Ce(2) is bonded in a distorted hexagonal planar geometry to two equivalent Co(2), four equivalent Co(1), four equivalent Co(3), and eight equivalent Cu(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 12-coordinate geometry to one Ce(1), two equivalent Ce(2), one Co(1), two equivalent Co(2), two equivalent Co(3), and four equivalent Cu(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), two equivalent Co(1), two equivalent Cu(1), and four equivalent Cu(2) atoms. In the third Co site, Co(3) is bonded to four equivalent Ce(2), four equivalent Co(1), and four equivalent Cu(2) atoms to form CoCe4Co4Cu4 cuboctahedra that share corners with four equivalent Co(3)Ce4Co4Cu4 cuboctahedra, corners with four equivalent Cu(1)Ce4Co4Cu4 cuboctahedra, corners with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra, edges with two equivalent Co(3)Ce4Co4Cu4 cuboctahedra, edges with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra, faces with two equivalent Co(3)Ce4Co4Cu4 cuboctahedra, and faces with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent Ce(1), four equivalent Co(2), and four equivalent Cu(2) atoms to form CuCe4Co4Cu4 cuboctahedra that share corners with four equivalent Co(3)Ce4Co4Cu4 cuboctahedra, corners with four equivalent Cu(1)Ce4Co4Cu4 cuboctahedra, corners with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra, edges with two equivalent Cu(1)Ce4Co4Cu4 cuboctahedra, edges with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra, faces with two equivalent Cu(1)Ce4Co4Cu4 cuboctahedra, and faces with eight equivalent Cu(2)Ce4Co5Cu3 cuboctahedra.
