KCoKAg is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cobalt;potassium molecules and two KAg clusters. In each KAg cluster, K(1) is bonded in a single-bond geometry to one Ag(1) atom. The K(1)-Ag(1) bond length is 1.16 Å. Ag(1) is bonded in a single-bond geometry to one K(1) atom.
