Ag3As 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 As(1) atoms to form AgAg8As4 cuboctahedra that share corners with twelve equivalent Ag(1)Ag8As4 cuboctahedra, edges with eight equivalent Ag(1)Ag8As4 cuboctahedra, edges with eight equivalent Ag(2)Ag8As4 cuboctahedra, edges with eight equivalent As(1)Ag12 cuboctahedra, faces with four equivalent Ag(2)Ag8As4 cuboctahedra, faces with four equivalent As(1)Ag12 cuboctahedra, and faces with ten equivalent Ag(1)Ag8As4 cuboctahedra. In the second Ag site, Ag(2) is bonded to eight equivalent Ag(1) and four equivalent As(1) atoms to form AgAg8As4 cuboctahedra that share corners with four equivalent Ag(2)Ag8As4 cuboctahedra, corners with eight equivalent As(1)Ag12 cuboctahedra, edges with eight equivalent Ag(2)Ag8As4 cuboctahedra, edges with sixteen equivalent Ag(1)Ag8As4 cuboctahedra, faces with four equivalent Ag(2)Ag8As4 cuboctahedra, faces with six equivalent As(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(1)Ag8As4 cuboctahedra. As(1) is bonded to four equivalent Ag(2) and eight equivalent Ag(1) atoms to form AsAg12 cuboctahedra that share corners with four equivalent As(1)Ag12 cuboctahedra, corners with eight equivalent Ag(2)Ag8As4 cuboctahedra, edges with eight equivalent As(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Ag8As4 cuboctahedra, faces with four equivalent As(1)Ag12 cuboctahedra, faces with six equivalent Ag(2)Ag8As4 cuboctahedra, and faces with eight equivalent Ag(1)Ag8As4 cuboctahedra.
