The compound described by (Fe3P3O14)2O2 crystallizes in the monoclinic C2/c space group. The structure consists of four water atoms inside a Fe3P3O14 framework. In the Fe3P3O14 framework, there are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1), two equivalent O(6), and two equivalent O(8) atoms to form distorted FeO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent Fe(2)O5 trigonal bipyramids, and  an edgeedge with one P(2)O4 tetrahedra. In the second Fe site, Fe(2) is bonded to one O(3), one O(4), one O(5), one O(7), and one O(8) atom to form FeO5 trigonal bipyramids that share  a cornercorner with one Fe(1)O6 octahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with three equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(4), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one Fe(1)O6 octahedra and corners with three equivalent Fe(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 47°. In the second P site, P(2) is bonded to two equivalent O(5) and two equivalent O(8) atoms to form PO4 tetrahedra that share corners with four equivalent Fe(2)O5 trigonal bipyramids and  an edgeedge with one Fe(1)O6 octahedra. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Fe(2) and one P(1) atom. In the second O site, O(5) is bonded in a bent 150 degrees geometry to one Fe(2) and one P(2) atom. In the third O site, O(6) is bonded in a single-bond geometry to one Fe(1) atom. In the fourth O site, O(7) is bonded in a bent 150 degrees geometry to one Fe(2) and one P(1) atom. In the fifth O site, O(8) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one P(2) atom. In the sixth O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Fe(1) and one P(1) atom. In the seventh O site, O(3) is bonded in a bent 120 degrees geometry to one Fe(2) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
