Materials Data on Rb2Ti(WO4)3 by Materials Project
Rb2Ti(WO4)3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 3.08–3.46 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six WO6 octahedra. The corner-sharing octahedral tilt angles are 38°. There is two shorter (1.96 Å) and four longer (1.97 Å) Ti–O bond length. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with two equivalent TiO6 octahedra and corners with four WO6 octahedra. The corner-sharing octahedra tilt angles range from 38–39°. There are a spread of W–O bond distances ranging from 1.91–1.97 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with two equivalent TiO6 octahedra and corners with four equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 38–39°. There are a spread of W–O bond distances ranging from 1.91–1.97 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+ and two equivalent W6+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Ti4+, and one W6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Ti4+, and one W6+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+ and two W6+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Ti4+, and one W6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+ and two W6+ atoms.
