ReZnBr is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReZnBr clusters. Re(1) is bonded in a single-bond geometry to one Br(1) atom. The Re(1)-Br(1) bond length is 0.88 Å. Zn(1) is bonded in a single-bond geometry to one Br(1) atom. The Zn(1)-Br(1) bond length is 1.03 Å. Br(1) is bonded in a linear geometry to one Re(1) and one Zn(1) atom.
