Materials Data on Te2Pb3(ClO3)2 by Materials Project
Pb3Te2(O3Cl)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to eight O2- and one Cl1- atom. There are a spread of Pb–O bond distances ranging from 2.57–3.05 Å. The Pb–Cl bond length is 3.32 Å. In the second Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to four O2- and four Cl1- atoms. There are two shorter (2.46 Å) and two longer (2.61 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 3.23–3.30 Å. In the third Pb2+ site, Pb2+ is bonded in a 5-coordinate geometry to five O2- and three Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.44–2.70 Å. There are two shorter (3.32 Å) and one longer (3.33 Å) Pb–Cl bond lengths. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded to four O2- atoms to form distorted edge-sharing TeO4 trigonal pyramids. There are two shorter (1.96 Å) and two longer (2.08 Å) Te–O bond lengths. In the second Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. There is one shorter (1.88 Å) and two longer (1.91 Å) Te–O bond length. The Te–Cl bond length is 3.31 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Pb2+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three Pb2+ and one Te4+ atom. In the fourth O2- site, O2- is bonded to three Pb2+ and one Te4+ atom to form distorted edge-sharing OTePb3 tetrahedra. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four Pb2+ and one Te4+ atom. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms.
