The crystal structure described by Pr(RuAl5)2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 20-coordinate geometry to four equivalent Ru(1), two equivalent Al(2), two equivalent Al(4), four equivalent Al(1), four equivalent Al(3), and four equivalent Al(5) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Pr(1), two equivalent Al(1), two equivalent Al(2), two equivalent Al(3), two equivalent Al(4), and two equivalent Al(5) atoms. There are five inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Pr(1) and two equivalent Ru(1) atoms. In the second Al site, Al(2) is bonded in a 2-coordinate geometry to one Pr(1) and two equivalent Ru(1) atoms. In the third Al site, Al(3) is bonded in a 2-coordinate geometry to two equivalent Pr(1) and two equivalent Ru(1) atoms. In the fourth Al site, Al(4) is bonded in a 2-coordinate geometry to one Pr(1) and two equivalent Ru(1) atoms. In the fifth Al site, Al(5) is bonded in a distorted linear geometry to two equivalent Pr(1) and two equivalent Ru(1) atoms. is represented by the CIF file [CIF]
