PaRh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent Rh(1) atoms to form PaRh12 cuboctahedra that share corners with twelve equivalent Pa(1)Rh12 cuboctahedra, edges with twenty-four equivalent Rh(1)Pa4Rh8 cuboctahedra, faces with six equivalent Pa(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Pa4Rh8 cuboctahedra. Rh(1) is bonded to four equivalent Pa(1) and eight equivalent Rh(1) atoms to form distorted RhPa4Rh8 cuboctahedra that share corners with twelve equivalent Rh(1)Pa4Rh8 cuboctahedra, edges with eight equivalent Pa(1)Rh12 cuboctahedra, edges with sixteen equivalent Rh(1)Pa4Rh8 cuboctahedra, faces with four equivalent Pa(1)Rh12 cuboctahedra, and faces with fourteen equivalent Rh(1)Pa4Rh8 cuboctahedra.
