Materials Data on Zn2PHO5 by Materials Project
Zn2(OH)PO4 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with four equivalent PO4 tetrahedra, corners with four equivalent ZnO5 trigonal bipyramids, and edges with two equivalent ZnO6 octahedra. There are a spread of Zn–O bond distances ranging from 2.05–2.32 Å. In the second Zn2+ site, Zn2+ is bonded to five O2- atoms to form ZnO5 trigonal bipyramids that share corners with four equivalent ZnO6 octahedra, corners with four equivalent PO4 tetrahedra, and an edgeedge with one ZnO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 57–72°. There are a spread of Zn–O bond distances ranging from 2.02–2.08 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ZnO6 octahedra and corners with four equivalent ZnO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 55–61°. There is two shorter (1.56 Å) and two longer (1.57 Å) P–O bond length. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Zn2+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one P5+ atom.
