PaYb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent Yb(1) atoms to form PaYb12 cuboctahedra that share corners with twelve equivalent Pa(1)Yb12 cuboctahedra, edges with twenty-four equivalent Yb(1)Yb8Pa4 cuboctahedra, faces with six equivalent Pa(1)Yb12 cuboctahedra, and faces with twelve equivalent Yb(1)Yb8Pa4 cuboctahedra. Yb(1) is bonded to four equivalent Pa(1) and eight equivalent Yb(1) atoms to form distorted YbYb8Pa4 cuboctahedra that share corners with twelve equivalent Yb(1)Yb8Pa4 cuboctahedra, edges with eight equivalent Pa(1)Yb12 cuboctahedra, edges with sixteen equivalent Yb(1)Yb8Pa4 cuboctahedra, faces with four equivalent Pa(1)Yb12 cuboctahedra, and faces with fourteen equivalent Yb(1)Yb8Pa4 cuboctahedra.
