Pr6CoBr10 crystallizes in the triclinic P-1 space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to one Co(1), one Br(2), one Br(4), one Br(5), and two equivalent Br(1) atoms to form a mixture of corner and edge-sharing PrCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second Pr site, Pr(2) is bonded to one Co(1), one Br(1), one Br(4), one Br(5), and two equivalent Br(3) atoms to form a mixture of corner and edge-sharing PrCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the third Pr site, Pr(3) is bonded to one Co(1), one Br(1), one Br(3), one Br(5), and two equivalent Br(2) atoms to form a mixture of corner and edge-sharing PrCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. Co(1) is bonded in an octahedral geometry to two equivalent Pr(1), two equivalent Pr(2), and two equivalent Pr(3) atoms. There are five inequivalent Br sites. In the first Br site, Br(1) is bonded in a see-saw-like geometry to one Pr(2), one Pr(3), and two equivalent Pr(1) atoms. In the second Br site, Br(2) is bonded in a T-shaped geometry to one Pr(1) and two equivalent Pr(3) atoms. In the third Br site, Br(3) is bonded in a T-shaped geometry to one Pr(3) and two equivalent Pr(2) atoms. In the fourth Br site, Br(4) is bonded in an L-shaped geometry to one Pr(1) and one Pr(2) atom. In the fifth Br site, Br(5) is bonded in a 3-coordinate geometry to one Pr(1), one Pr(2), and one Pr(3) atom.
