AlH10O4F5H2O crystallizes in the monoclinic Pc space group. The structure is three-dimensional and consists of two water molecules and one AlH10O4F5 framework. In the AlH10O4F5 framework, Al3+ is bonded to six F1- atoms to form corner-sharing AlF6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Al–F bond distances ranging from 1.81–1.88 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to one O2- and one F1- atom. The H–O bond length is 1.01 Å. The H–F bond length is 1.57 Å. In the second H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.01 Å. The H–F bond length is 1.54 Å. In the third H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.01 Å. The H–F bond length is 1.52 Å. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- and one F1- atom. The H–O bond length is 1.00 Å. The H–F bond length is 1.61 Å. In the fifth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- and one F1- atom. The H–O bond length is 1.00 Å. The H–F bond length is 1.61 Å. In the eighth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- and one F1- atom. The H–O bond length is 1.00 Å. The H–F bond length is 1.58 Å. In the ninth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.14 Å) and one longer (1.30 Å) H–O bond length. In the tenth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.19 Å) and one longer (1.22 Å) H–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Al3+ atoms. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to one Al3+ and one H1+ atom. In the third F1- site, F1- is bonded in a bent 120 degrees geometry to one Al3+ and one H1+ atom. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms. In the fifth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Al3+ and two H1+ atoms.
