(Zn3P2HO8)2(H2)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four molecular hydrogen molecules and one Zn3P2HO8 framework. In the Zn3P2HO8 framework, there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a trigonal planar geometry to one H and two equivalent O2- atoms. The Zn–H bond length is 1.55 Å. Both Zn–O bond lengths are 1.86 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with two equivalent ZnO4 tetrahedra and corners with four equivalent PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.94–2.03 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ZnO4 tetrahedra. There is three shorter (1.54 Å) and one longer (1.60 Å) P–O bond length. H is bonded in a single-bond geometry to one Zn2+ atom. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and one P5+ atom.
