Materials Data on RbHo(WO4)2 by Materials Project
RbHo(WO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.10 Å. Ho3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ho–O bond distances ranging from 2.27–2.32 Å. W6+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of W–O bond distances ranging from 1.84–2.14 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+, one Ho3+, and one W6+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Rb1+, one Ho3+, and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ho3+, and one W6+ atom.
