Materials Data on Rb2(TeO4)3 by Materials Project

Abstract

Rb2(TeO4)3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb is bonded to six O atoms to form distorted RbO6 octahedra that share corners with nine equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 64–72°. There are three shorter (3.08 Å) and three longer (3.43 Å) Rb–O bond lengths. Te is bonded to six O atoms to form TeO6 octahedra that share corners with four equivalent TeO6 octahedra and corners with six equivalent RbO6 octahedra. The corner-sharing octahedra tilt angles range from 53–72°. There is two shorter (1.92 Å) and four longer (1.99 Å) Te–O bond length. There are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Rb and one Te atom. In the second O site, O is bonded in a distorted trigonal planar geometry to one Rb and two equivalent Te atoms.
