AlH5(SeO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Al3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Al–O bond distances ranging from 1.88–1.98 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.78 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two H1+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one H1+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Se4+ atom.
