YAg3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form YAg12 cuboctahedra that share corners with four equivalent Y(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Y4Ag8 cuboctahedra, corners with sixteen equivalent Ag(1)Y4Ag4 cuboctahedra, edges with eight equivalent Y(1)Ag12 cuboctahedra, edges with eight equivalent Ag(1)Y4Ag4 cuboctahedra, faces with four equivalent Y(1)Ag12 cuboctahedra, and faces with six equivalent Ag(2)Y4Ag8 cuboctahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Y(1) and four equivalent Ag(2) atoms to form distorted AgY4Ag4 cuboctahedra that share corners with eight equivalent Y(1)Ag12 cuboctahedra, corners with eight equivalent Ag(1)Y4Ag4 cuboctahedra, corners with eight equivalent Ag(2)Y4Ag8 cuboctahedra, edges with four equivalent Y(1)Ag12 cuboctahedra, edges with four equivalent Ag(2)Y4Ag8 cuboctahedra, edges with twelve equivalent Ag(1)Y4Ag4 cuboctahedra, and faces with six equivalent Ag(1)Y4Ag4 cuboctahedra. In the second Ag site, Ag(2) is bonded to four equivalent Y(1) and eight equivalent Ag(1) atoms to form AgY4Ag8 cuboctahedra that share corners with four equivalent Ag(2)Y4Ag8 cuboctahedra, corners with eight equivalent Y(1)Ag12 cuboctahedra, corners with sixteen equivalent Ag(1)Y4Ag4 cuboctahedra, edges with eight equivalent Ag(1)Y4Ag4 cuboctahedra, edges with eight equivalent Ag(2)Y4Ag8 cuboctahedra, faces with four equivalent Ag(2)Y4Ag8 cuboctahedra, and faces with six equivalent Y(1)Ag12 cuboctahedra.
