Zn Ga Ga Ru
RuZnGa2 crystallizes in the monoclinic Cm space group. Ru(1) is bonded to six equivalent Ru(1), one Ga(1), and one Ga(2) atom to form a mixture of distorted corner and edge-sharing RuGa2Ru6 hexagonal bipyramids. All Ru(1)-Ru(1) bond lengths are 2.95 Å. The Ru(1)-Ga(1) bond length is 3.09 Å. The Ru(1)-Ga(2) bond length is 3.09 Å. Zn(1) is bonded in a linear geometry to one Ga(1) and one Ga(2) atom. The Zn(1)-Ga(1) bond length is 1.51 Å. The Zn(1)-Ga(2) bond length is 0.78 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a single-bond geometry to one Ru(1) and one Zn(1) atom. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Ru(1) and one Zn(1) atom.
