RhReReAl is Cubane-derived structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three ReAl clusters and three RhRe clusters. In each ReAl cluster, Re(1) is bonded in a single-bond geometry to one Al(1) atom. The Re(1)-Al(1) bond length is 0.86 Å. Al(1) is bonded in a single-bond geometry to one Re(1) atom. In each RhRe cluster, Re(2) is bonded in a single-bond geometry to one Rh(1) atom. The Re(2)-Rh(1) bond length is 0.86 Å. Rh(1) is bonded in a single-bond geometry to one Re(2) atom.
