Abstract

Pb2InP3O11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.14–2.26 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Pb–O bond distances ranging from 2.41–2.80 Å. In the second Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.49–3.16 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 45–47°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent InO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–54°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent InO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one In3+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one In3+, one Pb2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one In3+, one Pb2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one In3+, one Pb2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one In3+, one Pb2+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one In3+, two Pb2+, and one P5+ atom.
