The material described by AgPb3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ag(1) is bonded to twelve equivalent Pb(1) atoms to form AgPb12 cuboctahedra that share corners with six equivalent Ag(1)Pb12 cuboctahedra, corners with twelve equivalent Pb(1)Ag4Pb8 cuboctahedra, edges with eighteen equivalent Pb(1)Ag4Pb8 cuboctahedra, faces with eight equivalent Ag(1)Pb12 cuboctahedra, and faces with twelve equivalent Pb(1)Ag4Pb8 cuboctahedra. Pb(1) is bonded to four equivalent Ag(1) and eight equivalent Pb(1) atoms to form distorted PbAg4Pb8 cuboctahedra that share corners with four equivalent Ag(1)Pb12 cuboctahedra, corners with fourteen equivalent Pb(1)Ag4Pb8 cuboctahedra, edges with six equivalent Ag(1)Pb12 cuboctahedra, edges with twelve equivalent Pb(1)Ag4Pb8 cuboctahedra, faces with four equivalent Ag(1)Pb12 cuboctahedra, and faces with sixteen equivalent Pb(1)Ag4Pb8 cuboctahedra. is represented by the CIF card [CIF]
