Materials Data on B5H2Pb2O11 by Materials Project

B5Pb2H2O11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are five inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.35–1.39 Å. In the second B site, B is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.36 Å) and two longer (1.38 Å) B–O bond length. In the third B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.47–1.50 Å. In the fourth B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.46–1.52 Å.

Materials Data on BH(PbO2)2 by Materials Project

BH(PbO2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.41 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (2.25 Å) and two longer (2.32 Å) Pb–O bond lengths. In the second Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (2.28 Å) and two longer (2.34 Å) Pb–O bond lengths. H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 Å) H–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one B3+, one Pb2+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one B3+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one B3+ and one Pb2+ atom. In the fourth O2- site, O2- is bonded to four Pb2+ atoms to form edge-sharing OPb4 tetrahedra.
