The crystal structure described by NbOsPb is half-Heusler structured and crystallizes in the cubic F-43m space group. Nb(1) is bonded in a body-centered cubic geometry to four equivalent Os(1) and four equivalent Pb(1) atoms. Os(1) is bonded to four equivalent Nb(1) atoms to form distorted OsNb4 tetrahedra that share corners with four equivalent Pb(1)Nb4 tetrahedra, corners with twelve equivalent Os(1)Nb4 tetrahedra, and edges with six equivalent Pb(1)Nb4 tetrahedra. Pb(1) is bonded to four equivalent Nb(1) atoms to form distorted PbNb4 tetrahedra that share corners with four equivalent Os(1)Nb4 tetrahedra, corners with twelve equivalent Pb(1)Nb4 tetrahedra, and edges with six equivalent Os(1)Nb4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
