Materials Data on PbBr2 by Materials Project
PbBr2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pb2+ is bonded in a 7-coordinate geometry to seven Br1- atoms. There are a spread of Pb–Br bond distances ranging from 2.91–3.58 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 3-coordinate geometry to three equivalent Pb2+ atoms. In the second Br1- site, Br1- is bonded to four equivalent Pb2+ atoms to form a mixture of distorted corner and edge-sharing BrPb4 tetrahedra.
