Rb3Ag is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to eight equivalent Rb(1) and four equivalent Ag(1) atoms to form distorted RbRb8Ag4 cuboctahedra that share corners with twelve equivalent Rb(1)Rb8Ag4 cuboctahedra, edges with eight equivalent Ag(1)Rb12 cuboctahedra, edges with sixteen equivalent Rb(1)Rb8Ag4 cuboctahedra, faces with four equivalent Ag(1)Rb12 cuboctahedra, and faces with fourteen equivalent Rb(1)Rb8Ag4 cuboctahedra. Ag(1) is bonded to twelve equivalent Rb(1) atoms to form AgRb12 cuboctahedra that share corners with twelve equivalent Ag(1)Rb12 cuboctahedra, edges with twenty-four equivalent Rb(1)Rb8Ag4 cuboctahedra, faces with six equivalent Ag(1)Rb12 cuboctahedra, and faces with twelve equivalent Rb(1)Rb8Ag4 cuboctahedra.
