Materials Data on RbAl(SeO4)2 by Materials Project
RbAl(SeO4)2 crystallizes in the trigonal P321 space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent O2- atoms to form distorted RbO6 cuboctahedra that share corners with six equivalent SeO4 tetrahedra and edges with six equivalent RbO6 cuboctahedra. All Rb–O bond lengths are 3.12 Å. Al3+ is bonded to six equivalent O2- atoms to form distorted AlO6 pentagonal pyramids that share corners with six equivalent SeO4 tetrahedra. All Al–O bond lengths are 1.93 Å. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with three equivalent RbO6 cuboctahedra and corners with three equivalent AlO6 pentagonal pyramids. There is one shorter (1.65 Å) and three longer (1.67 Å) Se–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Se6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one Se6+ atom.
