Ge7H4O17(H5O2)2(H2O)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of two molecular hydrogen;dihydrate molecules, two water molecules, and one Ge7H4O17 framework. In the Ge7H4O17 framework, there are seven inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with three GeO4 tetrahedra and edges with three GeO6 octahedra. There are a spread of Ge–O bond distances ranging from 1.85–2.07 Å. In the second Ge4+ site, Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with three GeO4 tetrahedra and edges with three GeO6 octahedra. There are a spread of Ge–O bond distances ranging from 1.84–2.00 Å. In the third Ge4+ site, Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with three GeO4 tetrahedra and edges with three GeO6 octahedra. There are a spread of Ge–O bond distances ranging from 1.85–2.03 Å. In the fourth Ge4+ site, Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with three GeO4 tetrahedra and edges with three GeO6 octahedra. There are a spread of Ge–O bond distances ranging from 1.84–2.10 Å. In the fifth Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–64°. There are a spread of Ge–O bond distances ranging from 1.74–1.85 Å. In the sixth Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–61°. There are a spread of Ge–O bond distances ranging from 1.75–1.79 Å. In the seventh Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–59°. There are a spread of Ge–O bond distances ranging from 1.73–1.86 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.63 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 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. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are seventeen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Ge4+ atoms. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to three Ge4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Ge4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ge4+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two Ge4+ and one H1+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Ge4+ and one H1+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the twelfth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the thirteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the fourteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the fifteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the sixteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the seventeenth O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms.
