Materials Data on Fe3(PO4)4 by Materials Project
Fe3(PO4)4 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Fe3(PO4)4 sheet oriented in the (0, 1, 0) direction. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with four FeO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 58–59°. There are a spread of Fe–O bond distances ranging from 1.93–2.11 Å. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with two FeO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 58–59°. There are a spread of Fe–O bond distances ranging from 1.96–2.15 Å. In the third Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with two FeO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–59°. There are a spread of Fe–O bond distances ranging from 1.97–2.15 Å. In the fourth Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with four FeO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–59°. There are a spread of Fe–O bond distances ranging from 1.93–2.11 Å. There are four inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with four FeO6 octahedra and an edgeedge with one FeO6 octahedra. The corner-sharing octahedra tilt angles range from 36–52°. There is two shorter (1.52 Å) and two longer (1.60 Å) P–O bond length. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with four FeO6 octahedra and an edgeedge with one FeO6 octahedra. The corner-sharing octahedra tilt angles range from 36–53°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. In the third P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There are a spread of P–O bond distances ranging from 1.53–1.55 Å. In the fourth P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There is three shorter (1.54 Å) and one longer (1.55 Å) P–O bond length. There are sixteen inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one P atom. In the second O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one Fe and one P atom. In the fourth O site, O is bonded in a single-bond geometry to one P atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the sixth O site, O is bonded in a distorted trigonal planar geometry to two Fe and one P atom. In the seventh O site, O is bonded in a bent 120 degrees geometry to one Fe and one P atom. In the eighth O site, O is bonded in a distorted trigonal planar geometry to two Fe and one P atom. In the ninth O site, O is bonded in a bent 120 degrees geometry to one Fe and one P atom. In the tenth O site, O is bonded in a bent 120 degrees geometry to one Fe and one P atom. In the eleventh O site, O is bonded in a distorted trigonal planar geometry to two Fe and one P atom. In the twelfth O site, O is bonded in a bent 120 degrees geometry to one Fe and one P atom. In the thirteenth O site, O is bonded in a distorted trigonal planar geometry to two Fe and one P atom. In the fourteenth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the fifteenth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the sixteenth O site, O is bonded in a distorted bent 150 degrees geometry to one Fe and one P atom.
