Materials Data on ZnPH7C2N4O5 by Materials Project
ZnPO4C2N4H7O crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four ureidodiaminomethylium molecules and one ZnPO4 sheet oriented in the (0, 0, 1) direction. In the ZnPO4 sheet, 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 are a spread of P–O bond distances ranging from 1.54–1.60 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to 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.
