Pr3CoBr3 crystallizes in the cubic I4_132 space group. Pr(1) is bonded to two equivalent Co(1) and four equivalent Br(1) atoms to form a mixture of edge and corner-sharing PrCo2Br4 octahedra. The corner-sharing octahedral tilt angles range from 6-10°. Co(1) is bonded to six equivalent Pr(1) atoms to form edge-sharing CoPr6 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 6-10°. Both Pr(1)-Co(1) bond lengths are 2.79 Å. There are two shorter (3.11 Å) and two longer (3.24 Å) Pr(1)-Br(1) bond lengths. Co(1) is bonded to six equivalent Pr(1) atoms to form edge-sharing CoPr6 octahedra. Br(1) is bonded in a rectangular see-saw-like geometry to four equivalent Pr(1) atoms.
