Materials Data on AgPbBrO by Materials Project

Abstract

AgBrPbO crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one AgBr sheet oriented in the (0, 0, 1) direction and one PbO sheet oriented in the (0, 0, 1) direction. In the AgBr sheet, Ag1+ is bonded to five equivalent Br1- atoms to form a mixture of corner and edge-sharing AgBr5 square pyramids. There are four shorter (2.86 Å) and one longer (2.94 Å) Ag–Br bond lengths. Br1- is bonded to five equivalent Ag1+ atoms to form a mixture of corner and edge-sharing BrAg5 square pyramids. In the PbO sheet, Pb2+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Pb–O bond lengths are 2.35 Å. O2- is bonded to four equivalent Pb2+ atoms to form a mixture of corner and edge-sharing OPb4 tetrahedra.
