Pr3Br crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a distorted see-saw-like geometry to four equivalent Br(1) atoms. Br(1) is bonded to twelve equivalent Pr(1) atoms to form a mixture of corner and face-sharing BrPr12 cuboctahedra.
Pr3Br crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded in a distorted see-saw-like geometry to four equivalent Br(1) atoms. There are two shorter (3.47 Å) and two longer (3.61 Å) Pr(1)-Br(1) bond lengths. Br(1) is bonded to twelve equivalent Pr(1) atoms to form a mixture of corner and face-sharing BrPr12 cuboctahedra.
