Cu Cu Ru Rh
RuRhCu2 crystallizes in the triclinic P1 space group. Ru(1) is bonded in a 1-coordinate geometry to three equivalent Rh(1), one Cu(1), and one Cu(2) atom. There are a spread of Ru(1)-Rh(1) bond distances ranging from 2.24-3.02 Å. The Ru(1)-Cu(1) bond length is 0.65 Å. The Ru(1)-Cu(2) bond length is 1.42 Å. Rh(1) is bonded in a 13-coordinate geometry to three equivalent Ru(1), two equivalent Rh(1), three equivalent Cu(1), and five equivalent Cu(2) atoms. Both Rh(1)-Rh(1) bond lengths are 2.70 Å. There are a spread of Rh(1)-Cu(1) bond distances ranging from 2.29-3.02 Å. There are a spread of Rh(1)-Cu(2) bond distances ranging from 2.67-3.46 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Ru(1) and three equivalent Rh(1) atoms. In the second Cu site, Cu(2) is bonded in a single-bond geometry to one Ru(1) and five equivalent Rh(1) atoms.
