Hf Cd Ni Pb
HfNiCdPb crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 11-coordinate geometry to three equivalent Ni(1), four equivalent Cd(1), and four equivalent Pb(1) atoms. All Hf(1)-Ni(1) bond lengths are 2.92 Å. There are three shorter (2.82 Å) and one longer (3.49 Å) Hf(1)-Cd(1) bond length. There are three shorter (2.82 Å) and one longer (3.49 Å) Hf(1)-Pb(1) bond length. Ni(1) is bonded in a single-bond geometry to three equivalent Hf(1), three equivalent Cd(1), and one Pb(1) atom. All Ni(1)-Cd(1) bond lengths are 2.82 Å. The Ni(1)-Pb(1) bond length is 1.34 Å. Cd(1) is bonded in a 10-coordinate geometry to four equivalent Hf(1), three equivalent Ni(1), and three equivalent Pb(1) atoms. All Cd(1)-Pb(1) bond lengths are 2.92 Å. Pb(1) is bonded in a single-bond geometry to four equivalent Hf(1), one Ni(1), and three equivalent Cd(1) atoms.
