Re Re Ag Rh
RhReReAg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReAg clusters and two RhRe clusters. In each ReAg cluster, Re(2) is bonded in a single-bond geometry to one Ag(1) atom. The Re(2)-Ag(1) bond length is 0.81 Å. Ag(1) is bonded in a single-bond geometry to one Re(2) atom. In each RhRe cluster, Re(1) is bonded in a single-bond geometry to one Rh(1) atom. The Re(1)-Rh(1) bond length is 1.27 Å. Rh(1) is bonded in a distorted single-bond geometry to one Re(1) atom.
