Materials Data on PbIO by Materials Project

PbOI crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of four hydriodic acid molecules and two PbO ribbons oriented in the (1, 0, 0) direction. In each PbO ribbon, Pb is bonded in a distorted trigonal non-coplanar geometry to three equivalent O atoms. There are two shorter (2.24 Å) and one longer (2.31 Å) Pb–O bond lengths. O is bonded in a trigonal non-coplanar geometry to three equivalent Pb atoms.
