Materials Data on PbCl2 by Materials Project

Abstract

PbCl2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Pb–Cl bond distances ranging from 2.91–3.39 Å. In the second Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Pb–Cl bond distances ranging from 2.95–3.29 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms. In the third Cl1- site, Cl1- is bonded to four Pb2+ atoms to form a mixture of distorted corner and edge-sharing ClPb4 tetrahedra. In the fourth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms.
