K2AgAs is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2AgAs clusters. K(1) is bonded in a distorted single-bond geometry to one As(1) atom. The K(1)-As(1) bond length is 2.13 Å. Ag(1) is bonded in a single-bond geometry to one As(1) atom. The Ag(1)-As(1) bond length is 0.27 Å. As(1) is bonded in a single-bond geometry to two equivalent K(1) and one Ag(1) atom.
