YWAg3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Y(1) is bonded to twelve equivalent Ag(1) atoms to form YAg12 cuboctahedra that share corners with twelve equivalent Y(1)Ag12 cuboctahedra, faces with six equivalent Y(1)Ag12 cuboctahedra, and faces with eight equivalent W(1)Ag6 octahedra. There are a spread of Y(1)-Ag(1) bond distances ranging from 3.42-3.71 Å. W(1) is bonded to six equivalent Ag(1) atoms to form WAg6 octahedra that share corners with six equivalent W(1)Ag6 octahedra and faces with eight equivalent Y(1)Ag12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.42 Å) and three longer (2.62 Å) W(1)-Ag(1) bond lengths. Ag(1) is bonded in a 2-coordinate geometry to four equivalent Y(1) and two equivalent W(1) atoms.
