Ru2RhZn crystallizes in the triclinic P1 space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 9-coordinate geometry to two equivalent Ru(2), six equivalent Ru(1), and one Rh(1) atom. There is one shorter (2.17 Å) and one longer (2.50 Å) Ru(1)-Ru(2) bond length. There are four shorter (2.70 Å) and two longer (2.78 Å) Ru(1)-Ru(1) bond lengths. The Ru(1)-Rh(1) bond length is 3.42 Å. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to two equivalent Ru(1) and one Zn(1) atom. The Ru(2)-Zn(1) bond length is 2.41 Å. Rh(1) is bonded in a 2-coordinate geometry to one Ru(1) and two equivalent Zn(1) atoms. There is one shorter (1.94 Å) and one longer (2.31 Å) Rh(1)-Zn(1) bond length. Zn(1) is bonded in a 1-coordinate geometry to one Ru(2) and two equivalent Rh(1) atoms.
