Br Br Br Br
Br is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Br cluster. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted bent 150 degrees geometry to one Br(1) and one Br(2) atom. The Br(1)-Br(1) bond length is 2.33 Å. The Br(1)-Br(2) bond length is 1.13 Å. In the second Br site, Br(2) is bonded in a distorted single-bond geometry to one Br(1) atom.
