Sr2CoAg is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2CoAg clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Ag(1) atom. The Sr(1)-Ag(1) bond length is 0.97 Å. In the second Sr site, Sr(2) is bonded in a linear geometry to one Co(1) and one Ag(1) atom. The Sr(2)-Co(1) bond length is 0.65 Å. The Sr(2)-Ag(1) bond length is 0.97 Å. Co(1) is bonded in a single-bond geometry to one Sr(2) atom. Ag(1) is bonded in a linear geometry to one Sr(1) and one Sr(2) atom.
