PaCo3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent Co(1) atoms to form PaCo12 cuboctahedra that share corners with twelve equivalent Pa(1)Co12 cuboctahedra, edges with twenty-four equivalent Co(1)Pa4Co8 cuboctahedra, faces with six equivalent Pa(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Pa4Co8 cuboctahedra. Co(1) is bonded to four equivalent Pa(1) and eight equivalent Co(1) atoms to form CoPa4Co8 cuboctahedra that share corners with twelve equivalent Co(1)Pa4Co8 cuboctahedra, edges with eight equivalent Pa(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Pa4Co8 cuboctahedra, faces with four equivalent Pa(1)Co12 cuboctahedra, and faces with fourteen equivalent Co(1)Pa4Co8 cuboctahedra.
