Ga Si Ru Ru
(Ru)2SiGa crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ru clusters and two SiGa clusters. In each Ru cluster, Ru(1) is bonded in a single-bond geometry to one Ru(1) atom. The Ru(1)-Ru(1) bond length is 0.66 Å. In each SiGa cluster, Ga(1) is bonded in a single-bond geometry to one Si(1) atom. The Ga(1)-Si(1) bond length is 0.66 Å. Si(1) is bonded in a single-bond geometry to one Ga(1) atom.
