Br is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two hbr bromine molecules. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a single-bond geometry to one Br(2) atom. The Br(1)-Br(2) bond length is 1.31 Å. In the second Br site, Br(2) is bonded in a linear geometry to one Br(1) and one Br(3) atom. The Br(2)-Br(3) bond length is 1.12 Å. In the third Br site, Br(3) is bonded in a single-bond geometry to one Br(2) atom.
