Hf Sc Pb
ScHfPb crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a single-bond geometry to one Hf(1) and one Pb(1) atom. The Sc(1)-Hf(1) bond length is 0.16 Å. The Sc(1)-Pb(1) bond length is 3.67 Å. Hf(1) is bonded in a single-bond geometry to one Sc(1) and one Pb(1) atom. The Hf(1)-Pb(1) bond length is 3.43 Å. Pb(1) is bonded to one Sc(1), one Hf(1), and four equivalent Pb(1) atoms to form a mixture of distorted edge and corner-sharing PbHfScPb4 octahedra. The corner-sharing octahedra are not tilted. All Pb(1)-Pb(1) bond lengths are 3.25 Å.
