PuPa2Pr is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three PuPa2Pr clusters. Pu(1) is bonded in a linear geometry to one Pa(1) and one Pa(2) atom. The Pu(1)-Pa(1) bond length is 1.55 Å. The Pu(1)-Pa(2) bond length is 1.55 Å. There are two inequivalent Pa sites. In the first Pa site, Pa(1) is bonded in a linear geometry to one Pu(1) and one Pr(1) atom. The Pa(1)-Pr(1) bond length is 1.55 Å. In the second Pa site, Pa(2) is bonded in a single-bond geometry to one Pu(1) atom. Pr(1) is bonded in a single-bond geometry to one Pa(1) atom.
