Abstract

AgPb2OCl3F crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Ag2+ is bonded to six Cl1- atoms to form corner-sharing AgCl6 octahedra. The corner-sharing octahedra tilt angles range from 43–47°. There are a spread of Ag–Cl bond distances ranging from 2.71–2.77 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to one O2-, one Cl1-, and two equivalent F1- atoms. The Pb–O bond length is 2.34 Å. The Pb–Cl bond length is 3.19 Å. Both Pb–F bond lengths are 2.40 Å. In the second Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to two equivalent O2-, one Cl1-, and one F1- atom. Both Pb–O bond lengths are 2.31 Å. The Pb–Cl bond length is 3.16 Å. The Pb–F bond length is 2.59 Å. O2- is bonded in a 4-coordinate geometry to three Pb2+ and one F1- atom. The O–F bond length is 2.81 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to two equivalent Ag2+ and two equivalent Pb2+ atoms. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to two equivalent Ag2+ and two equivalent Pb2+ atoms. In the third Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent Ag2+ atoms. F1- is bonded in a 4-coordinate geometry to three Pb2+ and one O2- atom.
