Ce3Ru2In3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1), two equivalent In(2), and five equivalent In(1) atoms. In the second Ce site, Ce(2) is bonded in a 10-coordinate geometry to two equivalent Ru(1), four equivalent In(1), and four equivalent In(2) atoms. Ru(1) is bonded in a 1-coordinate geometry to one Ce(2), two equivalent Ce(1), and three equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 12-coordinate geometry to two equivalent Ce(2), five equivalent Ce(1), three equivalent Ru(1), and two equivalent In(2) atoms. In the second In site, In(2) is bonded to four equivalent Ce(1), four equivalent Ce(2), and four equivalent In(1) atoms to form a mixture of corner and face-sharing InCe8In4 cuboctahedra.
