Ag3Cd is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Ag(1), four equivalent Ag(2), and four equivalent Cd(1) atoms to form AgCd4Ag8 cuboctahedra that share corners with twelve equivalent Ag(1)Cd4Ag8 cuboctahedra, edges with eight equivalent Ag(1)Cd4Ag8 cuboctahedra, edges with eight equivalent Ag(2)Cd4Ag8 cuboctahedra, edges with eight equivalent Cd(1)Ag12 cuboctahedra, faces with four equivalent Ag(2)Cd4Ag8 cuboctahedra, faces with four equivalent Cd(1)Ag12 cuboctahedra, and faces with ten equivalent Ag(1)Cd4Ag8 cuboctahedra. In the second Ag site, Ag(2) is bonded to eight equivalent Ag(1) and four equivalent Cd(1) atoms to form AgCd4Ag8 cuboctahedra that share corners with four equivalent Ag(2)Cd4Ag8 cuboctahedra, corners with eight equivalent Cd(1)Ag12 cuboctahedra, edges with eight equivalent Ag(2)Cd4Ag8 cuboctahedra, edges with sixteen equivalent Ag(1)Cd4Ag8 cuboctahedra, faces with four equivalent Ag(2)Cd4Ag8 cuboctahedra, faces with six equivalent Cd(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(1)Cd4Ag8 cuboctahedra. Cd(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form CdAg12 cuboctahedra that share corners with four equivalent Cd(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Cd4Ag8 cuboctahedra, edges with eight equivalent Cd(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Cd4Ag8 cuboctahedra, faces with four equivalent Cd(1)Ag12 cuboctahedra, faces with six equivalent Ag(2)Cd4Ag8 cuboctahedra, and faces with eight equivalent Ag(1)Cd4Ag8 cuboctahedra.
