The compound described by Cs3Ac is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cs(1) is bonded to eight equivalent Cs(1) and four equivalent Ac(1) atoms to form CsCs8Ac4 cuboctahedra that share corners with twelve equivalent Cs(1)Cs8Ac4 cuboctahedra, edges with eight equivalent Ac(1)Cs12 cuboctahedra, edges with sixteen equivalent Cs(1)Cs8Ac4 cuboctahedra, faces with four equivalent Ac(1)Cs12 cuboctahedra, and faces with fourteen equivalent Cs(1)Cs8Ac4 cuboctahedra. Ac(1) is bonded to twelve equivalent Cs(1) atoms to form AcCs12 cuboctahedra that share corners with twelve equivalent Ac(1)Cs12 cuboctahedra, edges with twenty-four equivalent Cs(1)Cs8Ac4 cuboctahedra, faces with six equivalent Ac(1)Cs12 cuboctahedra, and faces with twelve equivalent Cs(1)Cs8Ac4 cuboctahedra. is represented by the CIF file [CIF]
