Pu2PaRu crystallizes in the trigonal R3m space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a distorted hexagonal planar geometry to four equivalent Pa(1) and three equivalent Ru(1) atoms. There are three shorter (2.71 Å) and one longer (3.93 Å) Pu(1)-Pa(1) bond length. All Pu(1)-Ru(1) bond lengths are 2.71 Å. In the second Pu site, Pu(2) is bonded in a single-bond geometry to three equivalent Pa(1) and one Ru(1) atom. All Pu(2)-Pa(1) bond lengths are 2.71 Å. The Pu(2)-Ru(1) bond length is 0.32 Å. Pa(1) is bonded in a 11-coordinate geometry to three equivalent Pu(2), four equivalent Pu(1), and four equivalent Ru(1) atoms. There are three shorter (2.71 Å) and one longer (3.61 Å) Pa(1)-Ru(1) bond length. Ru(1) is bonded in a single-bond geometry to one Pu(2), three equivalent Pu(1), and four equivalent Pa(1) atoms.
