Materials Data on SiPb4(ClO)4 by Materials Project
Pb4Si(OCl)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 2-coordinate geometry to two O2- and three Cl1- atoms. There are one shorter (2.34 Å) and one longer (2.38 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 2.84–3.27 Å. In the second Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to two O2- and seven Cl1- atoms. There are one shorter (2.41 Å) and one longer (2.56 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 2.90–3.65 Å. In the third Pb2+ site, Pb2+ is bonded in a 2-coordinate geometry to two O2- and three Cl1- atoms. There are one shorter (2.30 Å) and one longer (2.33 Å) Pb–O bond lengths. There are a spread of Pb–Cl bond distances ranging from 2.93–3.18 Å. In the fourth 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 2.52–2.59 Å. There are a spread of Pb–Cl bond distances ranging from 3.05–3.34 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.65 Å) and one longer (1.66 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+ and one Si4+ atom. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to five Pb2+ atoms. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to five Pb2+ atoms. In the third Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Pb2+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted square co-planar geometry to four Pb2+ atoms. In the fifth Cl1- site, Cl1- is bonded in a 6-coordinate geometry to six Pb2+ atoms.
