SrRu2Rh crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to one Ru(1), three equivalent Ru(2), and four equivalent Rh(1) atoms. The Sr(1)-Ru(1) bond length is 1.02 Å. All Sr(1)-Ru(2) bond lengths are 2.69 Å. There are three shorter (2.76 Å) and one longer (3.10 Å) Sr(1)-Rh(1) bond length. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Sr(1), four equivalent Ru(2), and three equivalent Rh(1) atoms. There are three shorter (2.76 Å) and one longer (3.10 Å) Ru(1)-Ru(2) bond length. All Ru(1)-Rh(1) bond lengths are 2.69 Å. In the second Ru site, Ru(2) is bonded in a 10-coordinate geometry to three equivalent Sr(1), four equivalent Ru(1), and three equivalent Rh(1) atoms. All Ru(2)-Rh(1) bond lengths are 2.69 Å. Rh(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1), three equivalent Ru(1), and three equivalent Ru(2) atoms.
