Pr3OsBr3 crystallizes in the cubic I4_132 space group. Pr(1) is bonded to two equivalent Os(1) and four equivalent Br(1) atoms to form a mixture of corner and edge-sharing PrOs2Br4 octahedra. The corner-sharing octahedral tilt angles range from 5-8°. Os(1) is bonded to six equivalent Pr(1) atoms to form edge-sharing OsPr6 octahedra. Br(1) is bonded in a rectangular see-saw-like geometry to four equivalent Pr(1) atoms.

The corner-sharing octahedral tilt angles range from 5-8°. Both Pr(1)-Os(1) bond lengths are 2.84 Å. There are two shorter (3.12 Å) and two longer (3.22 Å) Pr(1)-Br(1) bond lengths. Os(1) is bonded to six equivalent Pr(1) atoms to form edge-sharing OsPr6 octahedra. Br(1) is bonded in a rectangular see-saw-like geometry to four equivalent Pr(1) atoms.
