Materials Data on SrPbO3 by Materials Project
SrPbO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.51–3.01 Å. Pb4+ is bonded to six O2- atoms to form corner-sharing PbO6 octahedra. The corner-sharing octahedra tilt angles range from 32–35°. All Pb–O bond lengths are 2.22 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sr2+ and two equivalent Pb4+ atoms to form distorted corner-sharing OSr2Pb2 tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+ and two equivalent Pb4+ atoms.
