Materials Data on InPb2I5 by Materials Project
InPb2I5 crystallizes in the tetragonal I4/mcm space group. The structure is two-dimensional and consists of four indium molecules and two Pb2I5 sheets oriented in the (0, 0, 1) direction. In each Pb2I5 sheet, Pb2+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Pb–I bond distances ranging from 3.16–3.61 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a square co-planar geometry to four equivalent Pb2+ atoms. In the second I1- site, I1- is bonded in a 3-coordinate geometry to three equivalent Pb2+ atoms.
