Ce3Ru2In2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 1-coordinate geometry to one Ru(2) and three equivalent In(1) atoms. In the second Ce site, Ce(2) is bonded in a 1-coordinate geometry to one Ru(1), two equivalent In(1), and three equivalent In(2) atoms. In the third Ce site, Ce(3) is bonded in a 6-coordinate geometry to three equivalent In(1) and three equivalent In(2) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 1-coordinate geometry to one Ce(2) and three equivalent In(1) atoms. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to one Ce(1) and three equivalent In(2) 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), three equivalent Ce(1), three equivalent Ce(3), three equivalent Ru(1), and one In(2) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to three equivalent Ce(2), three equivalent Ce(3), three equivalent Ru(2), and one In(1) atom.
