Materials Data on PbF4 by Materials Project

PbF4 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two PbF4 sheets oriented in the (0, 0, 1) direction. Pb4+ is bonded to six F1- atoms to form corner-sharing PbF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.00 Å) and four longer (2.19 Å) Pb–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Pb4+ atom. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Pb4+ atoms.
