K2YAg crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one Y(1) and three equivalent Ag(1) atoms. The K(1)-Y(1) bond length is 1.47 Å. There are a spread of K(1)-Ag(1) bond distances ranging from 3.58-4.06 Å. Y(1) is bonded in an L-shaped geometry to two equivalent K(1) and two equivalent Ag(1) atoms. There is one shorter (3.57 Å) and one longer (3.73 Å) Y(1)-Ag(1) bond length. Ag(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Y(1) atoms.
