RuCdGa2 crystallizes in the trigonal R3m space group. Ru(1) is bonded in a distorted single-bond geometry to one Cd(1), three equivalent Ga(1), and four equivalent Ga(2) atoms. The Ru(1)-Cd(1) bond length is 1.92 Å. All Ru(1)-Ga(1) bond lengths are 2.73 Å. There is one shorter (2.61 Å) and three longer (2.80 Å) Ru(1)-Ga(2) bond lengths. Cd(1) is bonded in a single-bond geometry to one Ru(1), three equivalent Ga(1), and three equivalent Ga(2) atoms. All Cd(1)-Ga(1) bond lengths are 2.73 Å. All Cd(1)-Ga(2) bond lengths are 2.73 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 7-coordinate geometry to three equivalent Ru(1), three equivalent Cd(1), and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 1.92 Å. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to four equivalent Ru(1), three equivalent Cd(1), and one Ga(1) atom.
