TaOsPb is half-Heusler structured and crystallizes in the cubic F-43m space group. Ta(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 Ta(1) atoms to form distorted OsTa4 tetrahedra that share corners with four equivalent Pb(1)Ta4 tetrahedra, corners with twelve equivalent Os(1)Ta4 tetrahedra, and edges with six equivalent Pb(1)Ta4 tetrahedra. Pb(1) is bonded to four equivalent Ta(1) atoms to form PbTa4 tetrahedra that share corners with four equivalent Os(1)Ta4 tetrahedra, corners with twelve equivalent Pb(1)Ta4 tetrahedra, and edges with six equivalent Os(1)Ta4 tetrahedra.
