Materials Data on RbPbF3 by Materials Project

RbPbF3 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of two RbPbF3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Rb–F bond distances ranging from 2.78–3.50 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Rb–F bond distances ranging from 2.78–3.52 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to five F1- atoms to form corner-sharing PbF5 square pyramids. There are a spread of Pb–F bond distances ranging from 2.25–2.45 Å. In the second Pb2+ site, Pb2+ is bonded to five F1- atoms to form corner-sharing PbF5 square pyramids. There are a spread of Pb–F bond distances ranging from 2.24–2.45 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to five Rb1+ and one Pb2+ atom. In the second F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Rb1+ and two equivalent Pb2+ atoms. In the third F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Rb1+ and two equivalent Pb2+ atoms. In the fourth F1- site, F1- is bonded in a 2-coordinate geometry to five Rb1+ and one Pb2+ atom. In the fifth F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Rb1+ and two equivalent Pb2+ atoms. In the sixth F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Rb1+ and two equivalent Pb2+ atoms.
