Materials Data on FeP3(HO2)6 by Materials Project
Fe(H2PO4)3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Fe3+ is bonded to six equivalent O2- atoms to form FeO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Fe–O bond lengths are 2.05 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 39°. There is two shorter (1.54 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 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one P5+ atom.
