Hf Ir Os Pb
HfOsIrPb crystallizes in the trigonal R3m space group. Hf(1) is bonded in a single-bond geometry to three equivalent Os(1), four equivalent Ir(1), and one Pb(1) atom. All Hf(1)-Os(1) bond lengths are 2.72 Å. There are three shorter (2.72 Å) and one longer (3.74 Å) Hf(1)-Ir(1) bond length. The Hf(1)-Pb(1) bond length is 0.15 Å. Os(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1), three equivalent Ir(1), and three equivalent Pb(1) atoms. All Os(1)-Ir(1) bond lengths are 2.72 Å. All Os(1)-Pb(1) bond lengths are 2.72 Å. Ir(1) is bonded in a distorted q6 geometry to four equivalent Hf(1), three equivalent Os(1), and three equivalent Pb(1) atoms. All Ir(1)-Pb(1) bond lengths are 2.72 Å. Pb(1) is bonded in a single-bond geometry to one Hf(1), three equivalent Os(1), and three equivalent Ir(1) atoms.
