Hf In Pb Pb
HfInPb2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HfInPb2 cluster. Hf(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Pb(2) atom. The Hf(1)-Pb(1) bond length is 1.34 Å. The Hf(1)-Pb(2) bond length is 1.57 Å. In(1) is bonded in a single-bond geometry to one Pb(2) atom. The In(1)-Pb(2) bond length is 1.58 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Hf(1) atom. In the second Pb site, Pb(2) is bonded in a distorted bent 150 degrees geometry to one Hf(1) and one In(1) atom.
