Materials Data on Zn3P2(HO2)4 by Materials Project
Zn3P2(HO4)2H2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two hydrogen molecules and one Zn3P2(HO4)2 framework. In the Zn3P2(HO4)2 framework, there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a distorted linear geometry to two equivalent H and two equivalent O2- atoms. Both Zn–H bond lengths are 1.93 Å. Both Zn–O bond lengths are 1.90 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.94–2.07 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ZnO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.63 Å. 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 trigonal planar geometry to two Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom.
