Materials Data on Sb2Pb2O7 by Materials Project

Abstract

Pb2Sb2O7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–3.22 Å. In the second Pb2+ site, Pb2+ is bonded in a distorted linear geometry to two O2- atoms. Both Pb–O bond lengths are 1.72 Å. In the third Pb2+ site, Pb2+ is bonded in a linear geometry to two O2- atoms. Both Pb–O bond lengths are 1.66 Å. In the fourth Pb2+ site, Pb2+ is bonded in a distorted linear geometry to two O2- atoms. Both Pb–O bond lengths are 2.05 Å. There are four inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded in a distorted linear geometry to four O2- atoms. There is two shorter (1.43 Å) and two longer (2.49 Å) Sb–O bond length. In the second Sb5+ site, Sb5+ is bonded in a 4-coordinate geometry to four O2- atoms. There is two shorter (1.58 Å) and two longer (2.01 Å) Sb–O bond length. In the third Sb5+ site, Sb5+ is bonded in a distorted linear geometry to six O2- atoms. There are a spread of Sb–O bond distances ranging from 1.72–2.54 Å. In the fourth Sb5+ site, Sb5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.22 Å) and two longer (2.54 Å) Sb–O bond lengths. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pb2+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Sb5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pb2+ and two Sb5+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Pb2+ and two Sb5+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pb2+ and one Sb5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one Sb5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and two Sb5+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Pb2+ and two Sb5+ atoms. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pb2+ and two Sb5+ atoms. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and two Sb5+ atoms. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one Sb5+ atom. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to two Pb2+ and one Sb5+ atom. In the thirteenth O2- site, O2- is bonded in a 3-coordinate geometry to two Pb2+ and one Sb5+ atom.
