Materials Data on AgPbO3 by Materials Project

Abstract

AgPbO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ag2+ is bonded to six equivalent O2- atoms to form distorted AgO6 octahedra that share corners with nine equivalent PbO6 octahedra, edges with three equivalent AgO6 octahedra, and a faceface with one PbO6 octahedra. The corner-sharing octahedra tilt angles range from 47–63°. There are three shorter (2.28 Å) and three longer (2.39 Å) Ag–O bond lengths. Pb4+ is bonded to six equivalent O2- atoms to form distorted PbO6 octahedra that share corners with nine equivalent AgO6 octahedra, edges with three equivalent PbO6 octahedra, and a faceface with one AgO6 octahedra. The corner-sharing octahedra tilt angles range from 47–63°. There are three shorter (2.21 Å) and three longer (2.31 Å) Pb–O bond lengths. O2- is bonded to two equivalent Ag2+ and two equivalent Pb4+ atoms to form a mixture of distorted edge and corner-sharing OAg2Pb2 trigonal pyramids.
