Materials Data on TePb3Cl4O3 by Materials Project
Pb3TeO3Cl4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to three O2- and five Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.37–2.59 Å. There are a spread of Pb–Cl bond distances ranging from 2.96–3.60 Å. In the second Pb2+ site, Pb2+ is bonded in a 1-coordinate geometry to two O2- and five Cl1- atoms. There are one shorter (2.46 Å) and one longer (2.98 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 2.83–3.17 Å. In the third Pb2+ site, Pb2+ is bonded in a 2-coordinate geometry to two O2- and five Cl1- atoms. There are one shorter (2.44 Å) and one longer (2.49 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 2.86–3.27 Å. Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is two shorter (1.90 Å) and one longer (1.92 Å) Te–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+, one Te4+, and one Cl1- atom. The O–Cl bond length is 3.11 Å. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Pb2+ and one Te4+ atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to three Pb2+ atoms. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three Pb2+ atoms. In the third Cl1- site, Cl1- is bonded in a 6-coordinate geometry to five Pb2+ and one O2- atom. In the fourth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms.
