The material structure described by Ce5Ru3Al2 crystallizes in the cubic I2_13 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to three equivalent Ru(1) and one Al(1) atom to form distorted corner-sharing CeAlRu3 tetrahedra. In the second Ce site, Ce(2) is bonded in a 2-coordinate geometry to four equivalent Ru(1) and four equivalent Al(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), and two equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to one Ce(1), six equivalent Ce(2), and three equivalent Ru(1) atoms. is represented by the CIF file [CIF]
