The compound described by Ce4Ru3 crystallizes in the monoclinic C2/m space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to two equivalent Ru(2) and four equivalent Ru(1) atoms. In the second Ce site, Ce(2) is bonded in a 4-coordinate geometry to two equivalent Ru(1) and two equivalent Ru(2) atoms. In the third Ce site, Ce(3) is bonded in a 6-coordinate geometry to two equivalent Ru(2) and four equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to one Ce(2), two equivalent Ce(3), and four equivalent Ce(1) atoms. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to two equivalent Ce(2), two equivalent Ce(3), and four equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
