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 2-coordinate geometry to two equivalent Rh(1) and two equivalent Zn(1) atoms. There is one shorter (2.82 Å) and one longer (3.13 Å) Ru(1)-Rh(1) bond length. There is one shorter (1.91 Å) and one longer (2.34 Å) Ru(1)-Zn(1) bond length. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to two equivalent Rh(1) and one Zn(1) atom. There is one shorter (2.82 Å) and one longer (3.13 Å) Ru(2)-Rh(1) bond length. The Ru(2)-Zn(1) bond length is 2.40 Å. Rh(1) is bonded in a 10-coordinate geometry to two equivalent Ru(1), two equivalent Ru(2), and six equivalent Rh(1) atoms. There are four shorter (2.69 Å) and two longer (2.75 Å) Rh(1)-Rh(1) bond lengths. Zn(1) is bonded in a 1-coordinate geometry to one Ru(2) and two equivalent Ru(1) atoms.
