The compound described by HfPtPb is half-Heusler structured and crystallizes in the cubic F-43m space group. Hf(1) is bonded to six equivalent Pt(1) and four equivalent Pb(1) atoms to form a mixture of distorted face and corner-sharing HfPt6Pb4 tetrahedra. Pt(1) is bonded in a distorted q6 geometry to six equivalent Hf(1) and four equivalent Pb(1) atoms. Pb(1) is bonded in a body-centered cubic geometry to four equivalent Hf(1) and four equivalent Pt(1) atoms. is represented by the CIF card [CIF]
