Re Rh Br Br
ReRhBr2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReRhBr2 clusters. Re(1) is bonded in a linear geometry to one Br(1) and one Br(2) atom. The Re(1)-Br(1) bond length is 2.21 Å. The Re(1)-Br(2) bond length is 2.21 Å. Rh(1) is bonded in a single-bond geometry to one Br(1) atom. The Rh(1)-Br(1) bond length is 0.84 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted single-bond geometry to one Re(1) and one Rh(1) atom. In the second Br site, Br(2) is bonded in a distorted single-bond geometry to one Re(1) atom.
