Materials Data on Rb2SeO4 by Materials Project
Rb2SeO4 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to six O2- atoms to form RbO6 octahedra that share corners with six equivalent SeO4 tetrahedra and edges with two equivalent RbO6 octahedra. There are a spread of Rb–O bond distances ranging from 2.87–3.11 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.50 Å. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with six equivalent RbO6 octahedra. The corner-sharing octahedra tilt angles range from 39–55°. There is two shorter (1.67 Å) and two longer (1.69 Å) Se–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one Se6+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one Se6+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one Se6+ atom.
