Materials Data on RbPbIO6 by Materials Project
RbPbO6I is Hydrophilite-derived structured and crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. Rb is bonded to six equivalent O atoms to form distorted RbO6 pentagonal pyramids that share corners with six equivalent PbO6 octahedra and corners with six equivalent IO6 octahedra. The corner-sharing octahedra tilt angles range from 46–60°. All Rb–O bond lengths are 2.91 Å. Pb is bonded to six equivalent O atoms to form distorted PbO6 octahedra that share corners with six equivalent RbO6 pentagonal pyramids and edges with three equivalent IO6 octahedra. All Pb–O bond lengths are 2.22 Å. O is bonded in a distorted trigonal planar geometry to one Rb, one Pb, and one I atom. The O–I bond length is 1.92 Å. I is bonded to six equivalent O atoms to form IO6 octahedra that share corners with six equivalent RbO6 pentagonal pyramids and edges with three equivalent PbO6 octahedra.
