The compound described by Pr5Ru3Al2 crystallizes in the cubic I2_13 space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 2-coordinate geometry to four equivalent Ru(1) and four equivalent Al(1) atoms. In the second Pr site, Pr(2) is bonded to three equivalent Ru(1) and one Al(1) atom to form distorted corner-sharing PrAlRu3 tetrahedra. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Pr(2), four equivalent Pr(1), and two equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to one Pr(2), six equivalent Pr(1), and three equivalent Ru(1) atoms. is represented by the CIF card [CIF]
