Sr Ga Ga Co
SrCoGa2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrCoGa2 clusters. Sr(1) is bonded in a distorted linear geometry to one Ga(1) and one Ga(2) atom. The Sr(1)-Ga(1) bond length is 0.54 Å. The Sr(1)-Ga(2) bond length is 2.08 Å. Co(1) is bonded in a single-bond geometry to one Ga(1) atom. The Co(1)-Ga(1) bond length is 0.01 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to one Sr(1) and one Co(1) atom. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Sr(1) atom.
