The Materials Project

PbHfO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Hf4+ is bonded to six O2- atoms to form corner-sharing HfO6 octahedra. The corner-sharing octahedra tilt angles range from 19–22°. All Hf–O bond lengths are 2.10 Å. Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.57–3.10 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Hf4+ and three equivalent Pb2+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Hf4+ and three equivalent Pb2+ atoms.
