Pr2Bi crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Bi(1) atoms. In the second Pr site, Pr(2) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing PrBi5 trigonal bipyramids. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1) and five equivalent Pr(2) atoms.
Pr2Bi crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Bi(1) atoms. All Pr(1)-Pr(1) bond lengths are 3.30 Å. All Pr(1)-Bi(1) bond lengths are 3.44 Å. In the second Pr site, Pr(2) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing PrBi5 trigonal bipyramids. There is one shorter (3.34 Å) and four longer (3.39 Å) Pr(2)-Bi(1) bond lengths. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1) and five equivalent Pr(2) atoms.
