Pr Pa Pa V
Pa2PrV crystallizes in the trigonal R3m space group. There are two inequivalent Pa sites. In the first Pa site, Pa(1) is bonded in a single-bond geometry to one Pr(1) atom. The Pa(1)-Pr(1) bond length is 2.20 Å. In the second Pa site, Pa(2) is bonded in a distorted linear geometry to one Pr(1) and one V(1) atom. The Pa(2)-Pr(1) bond length is 2.20 Å. The Pa(2)-V(1) bond length is 2.20 Å. Pr(1) is bonded to one Pa(1), one Pa(2), and three equivalent V(1) atoms to form distorted PrPa2V3 trigonal bipyramids that share corners with six equivalent Pr(1)Pa2V3 trigonal bipyramids and  a cornercorner with one V(1)Pr3Pa trigonal pyramid. All Pr(1)-V(1) bond lengths are 2.99 Å. V(1) is bonded to one Pa(2) and three equivalent Pr(1) atoms to form distorted VPr3Pa trigonal pyramids that share  a cornercorner with one Pr(1)Pa2V3 trigonal bipyramid and corners with six equivalent V(1)Pr3Pa trigonal pyramids.
