Na Hf Cd Pb
NaHfCdPb crystallizes in the trigonal R3m space group. Na(1) is bonded to one Hf(1) and three equivalent Cd(1) atoms to form distorted NaHfCd3 trigonal pyramids that share  a cornercorner with one Cd(1)Na3HfPb trigonal bipyramid, corners with three equivalent Hf(1)NaCdPb3 trigonal bipyramids, corners with six equivalent Na(1)HfCd3 trigonal pyramids, and edges with three equivalent Pb(1)Hf3Cd trigonal pyramids. The Na(1)-Hf(1) bond length is 2.06 Å. All Na(1)-Cd(1) bond lengths are 3.00 Å. Hf(1) is bonded to one Na(1), one Cd(1), and three equivalent Pb(1) atoms to form distorted HfNaCdPb3 trigonal bipyramids that share corners with six equivalent Hf(1)NaCdPb3 trigonal bipyramids,  a cornercorner with one Pb(1)Hf3Cd trigonal pyramid, corners with three equivalent Na(1)HfCd3 trigonal pyramids, and edges with three equivalent Cd(1)Na3HfPb trigonal bipyramids. The Hf(1)-Cd(1) bond length is 2.06 Å. All Hf(1)-Pb(1) bond lengths are 3.00 Å. Cd(1) is bonded to three equivalent Na(1), one Hf(1), and one Pb(1) atom to form distorted CdNa3HfPb trigonal bipyramids that share corners with six equivalent Cd(1)Na3HfPb trigonal bipyramids,  a cornercorner with one Na(1)HfCd3 trigonal pyramid, corners with three equivalent Pb(1)Hf3Cd trigonal pyramids, and edges with three equivalent Hf(1)NaCdPb3 trigonal bipyramids. The Cd(1)-Pb(1) bond length is 2.06 Å. Pb(1) is bonded to three equivalent Hf(1) and one Cd(1) atom to form distorted PbHf3Cd trigonal pyramids that share  a cornercorner with one Hf(1)NaCdPb3 trigonal bipyramid, corners with three equivalent Cd(1)Na3HfPb trigonal bipyramids, corners with six equivalent Pb(1)Hf3Cd trigonal pyramids, and edges with three equivalent Na(1)HfCd3 trigonal pyramids.
