CsAc3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cs(1) is bonded to twelve equivalent Ac(1) atoms to form CsAc12 cuboctahedra that share corners with twelve equivalent Cs(1)Ac12 cuboctahedra, edges with twenty-four equivalent Ac(1)Cs4Ac8 cuboctahedra, faces with six equivalent Cs(1)Ac12 cuboctahedra, and faces with twelve equivalent Ac(1)Cs4Ac8 cuboctahedra. Ac(1) is bonded to four equivalent Cs(1) and eight equivalent Ac(1) atoms to form AcCs4Ac8 cuboctahedra that share corners with twelve equivalent Ac(1)Cs4Ac8 cuboctahedra, edges with eight equivalent Cs(1)Ac12 cuboctahedra, edges with sixteen equivalent Ac(1)Cs4Ac8 cuboctahedra, faces with four equivalent Cs(1)Ac12 cuboctahedra, and faces with fourteen equivalent Ac(1)Cs4Ac8 cuboctahedra.
