Materials Data on Zn2PH2CO7 by Materials Project
Zn2CPH2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Zn–O bond distances ranging from 1.95–2.59 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form distorted ZnO6 octahedra that share corners with two equivalent ZnO6 octahedra, corners with two equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Zn–O bond distances ranging from 2.03–2.41 Å. C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent ZnO6 octahedra and an edgeedge with one ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 48–60°. There is one shorter (1.55 Å) and three longer (1.56 Å) P–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.68 Å) H–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Zn2+, one P5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Zn2+, one C3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Zn2+ and one C3+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Zn2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two Zn2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Zn2+ and one P5+ atom.
