Abstract

B10Pb4O19Cl2 crystallizes in the orthorhombic Pnn2 space group. The structure is three-dimensional. there are five inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.47–1.50 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.39 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.38 Å) B–O bond length. In the fourth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.47–1.51 Å. In the fifth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.46–1.51 Å. There are two inequivalent Pb+2.50+ sites. In the first Pb+2.50+ site, Pb+2.50+ is bonded in a 9-coordinate geometry to seven O2- and two Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.52–3.11 Å. There are one shorter (2.91 Å) and one longer (3.18 Å) Pb–Cl bond lengths. In the second Pb+2.50+ site, Pb+2.50+ is bonded in a 10-coordinate geometry to eight O2- and two Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.61–3.09 Å. There are one shorter (3.10 Å) and one longer (3.13 Å) Pb–Cl bond lengths. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ and one Pb+2.50+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two B3+ and one Pb+2.50+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ and two Pb+2.50+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Pb+2.50+ and one Cl1- atom. The O–Cl bond length is 2.43 Å. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ and two Pb+2.50+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ and one Pb+2.50+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ and two Pb+2.50+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two B3+ and one Pb+2.50+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ and two Pb+2.50+ atoms. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ and two Pb+2.50+ atoms. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Pb+2.50+ and one O2- atom. In the second Cl1- site, Cl1- is bonded in a distorted rectangular see-saw-like geometry to four Pb+2.50+ atoms.
