Sr Ga Ga Ru
SrRuGa2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrRuGa2 clusters. Sr(1) is bonded in a 3-coordinate geometry to one Ru(1) and two equivalent Ga(1) atoms. The Sr(1)-Ru(1) bond length is 0.87 Å. Both Sr(1)-Ga(1) bond lengths are 1.14 Å. Ru(1) is bonded in a distorted single-bond geometry to one Sr(1) and two equivalent Ga(1) atoms. Both Ru(1)-Ga(1) bond lengths are 1.14 Å. Ga(1) is bonded in a 3-coordinate geometry to one Sr(1), one Ru(1), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 0.87 Å.
