Materials Data on RbPr(WO4)2 by Materials Project
RbPr(WO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.98–3.18 Å. Pr3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.40–2.86 Å. W6+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 41°. There are a spread of W–O bond distances ranging from 1.83–2.21 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two equivalent W6+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, two equivalent Pr3+, and one W6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Rb1+, one Pr3+, and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Pr3+, and one W6+ atom.
