The material structure described by PaIr3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent Ir(1) atoms to form PaIr12 cuboctahedra that share corners with twelve equivalent Pa(1)Ir12 cuboctahedra, edges with twenty-four equivalent Ir(1)Pa4Ir8 cuboctahedra, faces with six equivalent Pa(1)Ir12 cuboctahedra, and faces with twelve equivalent Ir(1)Pa4Ir8 cuboctahedra. Ir(1) is bonded to four equivalent Pa(1) and eight equivalent Ir(1) atoms to form distorted IrPa4Ir8 cuboctahedra that share corners with twelve equivalent Ir(1)Pa4Ir8 cuboctahedra, edges with eight equivalent Pa(1)Ir12 cuboctahedra, edges with sixteen equivalent Ir(1)Pa4Ir8 cuboctahedra, faces with four equivalent Pa(1)Ir12 cuboctahedra, and faces with fourteen equivalent Ir(1)Pa4Ir8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
