Re Re Re Re Rh Rh
Re2Rh crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Re2Rh clusters. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted single-bond geometry to one Re(2) atom. The Re(1)-Re(2) bond length is 1.19 Å. In the second Re site, Re(2) is bonded in a distorted single-bond geometry to one Re(1) and one Rh(1) atom. The Re(2)-Rh(1) bond length is 0.80 Å. Rh(1) is bonded in a single-bond geometry to one Re(2) atom.
