Ga Ga Ru Se
RuGa2Se is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RuGa2Se cluster. Ru(1) is bonded in a single-bond geometry to one Ga(1) and one Ga(2) atom. The Ru(1)-Ga(1) bond length is 1.29 Å. The Ru(1)-Ga(2) bond length is 0.58 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 3-coordinate geometry to one Ru(1), one Ga(2), and one Se(1) atom. The Ga(1)-Ga(2) bond length is 1.26 Å. The Ga(1)-Se(1) bond length is 1.69 Å. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Ru(1) and one Ga(1) atom. Se(1) is bonded in a distorted single-bond geometry to one Ga(1) atom.
