Al2(SeO4)3 crystallizes in the trigonal R3c space group. The structure is three-dimensional. there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. There is three shorter (1.90 Å) and three longer (1.91 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded in an octahedral geometry to six O2- atoms. There is three shorter (1.87 Å) and three longer (1.88 Å) Al–O bond length. Se6+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.77 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Se6+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Se6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Al3+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Se6+ atom.
