Materials Data on K2PbO3 by Materials Project
Abstract
K2PbO3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.69–3.11 Å. Pb4+ is bonded to five O2- atoms to form distorted edge-sharing PbO5 trigonal bipyramids. There are a spread of Pb–O bond distances ranging from 2.06–2.24 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent K1+ and two equivalent Pb4+ atoms to form a mixture of distorted edge, face, and corner-sharing OK4Pb2 octahedra. The corner-sharing octahedra tilt angles range from 37–52°. In the second O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Pb4+ atom.
