CoIn2Br crystallizes in the trigonal R3m space group. Co(1) is bonded in a 4-coordinate geometry to one In(2) and three equivalent Br(1) atoms. The Co(1)-In(2) bond length is 1.77 Å. All Co(1)-Br(1) bond lengths are 3.13 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Br(1) atom. The In(1)-Br(1) bond length is 1.77 Å. In the second In site, In(2) is bonded in a distorted linear geometry to one Co(1) and one Br(1) atom. The In(2)-Br(1) bond length is 1.77 Å. Br(1) is bonded in a linear geometry to three equivalent Co(1), one In(1), and one In(2) atom.
