Materials Data on CdPH6NO5 by Materials Project
CdPH2O5NH4 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of four ammonium molecules and two CdPH2O5 sheets oriented in the (0, 0, 1) direction. In each CdPH2O5 sheet, Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with four equivalent CdO6 octahedra, corners with three equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 68°. There are a spread of Cd–O bond distances ranging from 2.27–2.43 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent CdO6 octahedra and an edgeedge with one CdO6 octahedra. The corner-sharing octahedra tilt angles range from 38–59°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cd2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cd2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Cd2+ and two equivalent H1+ atoms.
