The structure described by NaIrPb is half-Heusler structured and crystallizes in the cubic F-43m space group. Na(1) is bonded in a body-centered cubic geometry to four equivalent Ir(1) and four equivalent Pb(1) atoms. Ir(1) is bonded to four equivalent Na(1) atoms to form IrNa4 tetrahedra that share corners with four equivalent Pb(1)Na4 tetrahedra, corners with twelve equivalent Ir(1)Na4 tetrahedra, and edges with six equivalent Pb(1)Na4 tetrahedra. Pb(1) is bonded to four equivalent Na(1) atoms to form PbNa4 tetrahedra that share corners with four equivalent Ir(1)Na4 tetrahedra, corners with twelve equivalent Pb(1)Na4 tetrahedra, and edges with six equivalent Ir(1)Na4 tetrahedra. is represented by the CIF card [CIF]
