The material described by PbBr2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. Pb(1) is bonded to six equivalent Br(1) atoms to form a mixture of edge and corner-sharing PbBr6 octahedra. The corner-sharing octahedral tilt angles are 49°. Br(1) is bonded in a distorted trigonal planar geometry to three equivalent Pb(1) atoms. is represented by the CIF card [CIF]
