Pr5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Pr site, Pr(2) is bonded to six equivalent Ge(1) atoms to form a mixture of distorted corner, edge, and face-sharing PrGe6 octahedra. The corner-sharing octahedral tilt angles are 35°. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Pr(2) and five equivalent Pr(1) atoms.
Pr5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Pr(1)-Ge(1) bond distances ranging from 3.06-3.65 Å. In the second Pr site, Pr(2) is bonded to six equivalent Ge(1) atoms to form a mixture of distorted corner, edge, and face-sharing PrGe6 octahedra. The corner-sharing octahedral tilt angles are 35°. All Pr(2)-Ge(1) bond lengths are 3.23 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Pr(2) and five equivalent Pr(1) atoms.
