CeCu5Sn crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 19-coordinate geometry to three equivalent Cu(2), three equivalent Cu(3), three equivalent Cu(4), six equivalent Cu(1), and four equivalent Sn(1) atoms. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to three equivalent Ce(1), one Cu(3), two equivalent Cu(1), two equivalent Cu(2), two equivalent Cu(4), and two equivalent Sn(1) atoms to form a mixture of edge, face, and corner-sharing CuCe3Cu7Sn2 cuboctahedra.

In the third Cu site, Cu(3) is bonded in a 11-coordinate geometry to three equivalent Ce(1), one Cu(4), two equivalent Cu(1), two equivalent Cu(2), and three equivalent Sn(1) atoms. In the fourth Cu site, Cu(4) is bonded in a 9-coordinate geometry to three equivalent Ce(1), one Cu(2), one Cu(3), four equivalent Cu(1), and one Sn(1) atom. Sn(1) is bonded in a 14-coordinate geometry to four equivalent Ce(1), one Cu(4), two equivalent Cu(2), three equivalent Cu(3), and four equivalent Cu(1) atoms.
