Ag3As is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ag(1) is bonded to eight equivalent Ag(1) and four equivalent As(1) atoms to form AgAg8As4 cuboctahedra that share corners with four equivalent As(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Ag8As4 cuboctahedra, edges with six equivalent As(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ag8As4 cuboctahedra, faces with four equivalent As(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Ag8As4 cuboctahedra. As(1) is bonded to twelve equivalent Ag(1) atoms to form AsAg12 cuboctahedra that share corners with six equivalent As(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ag8As4 cuboctahedra, edges with eighteen equivalent Ag(1)Ag8As4 cuboctahedra, faces with eight equivalent As(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ag8As4 cuboctahedra.

There are four shorter (2.95 Å) and four longer (2.97 Å) Ag(1)-Ag(1) bond lengths. There are two shorter (2.95 Å) and two longer (2.97 Å) Ag(1)-As(1) bond lengths. As(1) is bonded to twelve equivalent Ag(1) atoms to form AsAg12 cuboctahedra that share corners with six equivalent As(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ag8As4 cuboctahedra, edges with eighteen equivalent Ag(1)Ag8As4 cuboctahedra, faces with eight equivalent As(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ag8As4 cuboctahedra.
