Materials Data on Te3(PbO4)2 by Materials Project
Pb2Te3O8 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.42–3.10 Å. In the second Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.42–3.14 Å. There are four inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is one shorter (1.90 Å) and two longer (1.93 Å) Te–O bond length. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.37 Å. In the third Te4+ site, Te4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.89 Å) and one longer (1.92 Å) Te–O bond length. In the fourth Te4+ site, Te4+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.88 Å) and two longer (2.18 Å) Te–O bond lengths. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Pb2+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Pb2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Pb2+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and two Te4+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Te4+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to four Pb2+ and one Te4+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Te4+ atoms.
