Materials Data on H3Pb by Materials Project

(PbH2)2H2 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional and consists of two hydrogen molecules and one PbH2 framework. In the PbH2 framework, Pb is bonded in a body-centered cubic geometry to eight equivalent H atoms. All Pb–H bond lengths are 2.37 Å. H is bonded to four equivalent Pb atoms to form a mixture of corner and edge-sharing HPb4 tetrahedra.

Materials Data on HPb by Materials Project

PbH crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Pb is bonded in a distorted single-bond geometry to four equivalent H atoms. There are one shorter (2.25 Å) and three longer (2.51 Å) Pb–H bond lengths. H is bonded in a distorted rectangular see-saw-like geometry to four equivalent Pb atoms.
