Materials Data on FeP2O7 by Materials Project
FeP2O7 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Fe is bonded to five O atoms to form FeO5 trigonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.92–2.03 Å. There are two inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with two equivalent FeO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with three equivalent FeO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. There are seven inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the second O site, O is bonded in a bent 150 degrees geometry to two P atoms. 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 distorted bent 150 degrees geometry to one Fe and one P atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom. In the seventh O site, O is bonded in a bent 150 degrees geometry to one Fe and one P atom.
