Materials Data on Zn2P2H12O11 by Materials Project
(ZnP(HO)5)2H2O crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two water molecules and one ZnP(HO)5 framework. In the ZnP(HO)5 framework, there are three inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with two equivalent PHO3 tetrahedra. There are a spread of Zn–O bond distances ranging from 2.04–2.18 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PHO3 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.98–2.03 Å. In the third Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with two equivalent PHO3 tetrahedra. There are a spread of Zn–O bond distances ranging from 2.04–2.19 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one H+0.67+ and three O2- atoms to form distorted PHO3 tetrahedra that share a cornercorner with one ZnO6 octahedra and corners with two equivalent ZnO4 tetrahedra.

In the ninth H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the tenth H+0.67+ site, H+0.67+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.71 Å) H–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H+0.67+ atoms.
