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.
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. All Ce(1)-Ru(1) bond lengths are 2.81 Å. The Ce(1)-Al(1) bond length is 3.24 Å. 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. There are two shorter (2.77 Å) and two longer (3.28 Å) Ce(2)-Ru(1) bond lengths. There are two shorter (3.21 Å) and two longer (3.24 Å) Ce(2)-Al(1) bond lengths. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), and two equivalent Al(1) atoms. Both Ru(1)-Al(1) bond lengths are 2.62 Å. Al(1) is bonded in a 10-coordinate geometry to one Ce(1), six equivalent Ce(2), and three equivalent Ru(1) atoms.
