Pr5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. In the second Pr site, Pr(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing PrRu4 tetrahedra. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Pr(3), three equivalent Pr(1), and three equivalent Pr(2) atoms.
Pr5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Pr(1)-Ru(1) bond distances ranging from 2.77-3.60 Å. In the second Pr site, Pr(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing PrRu4 tetrahedra. There are two shorter (3.00 Å) and two longer (3.07 Å) Pr(3)-Ru(1) bond lengths. In the third Pr site, Pr(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Pr(2)-Ru(1) bond distances ranging from 2.87-3.24 Å. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Pr(3), three equivalent Pr(1), and three equivalent Pr(2) atoms.
