Materials Data on Pb2IO2 by Materials Project
(PbO)2I crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two hydriodic acid molecules and two PbO sheets oriented in the (0, 0, 1) direction. In each PbO sheet, Pb is bonded in a 4-coordinate geometry to four equivalent O atoms. All Pb–O bond lengths are 2.37 Å. O is bonded to four equivalent Pb atoms to form a mixture of corner and edge-sharing OPb4 tetrahedra.
