The crystal structure described by Fe5P3O13 crystallizes in the monoclinic P2_1/m space group. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(3), one O(4), one O(5), one O(8), and one O(9) atom to form FeO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, corners with two equivalent P(3)O4 tetrahedra,  a cornercorner with one Fe(2)O5 trigonal bipyramid, edges with two equivalent Fe(1)O6 octahedra,  an edgeedge with one Fe(2)O5 trigonal bipyramid, and  an edgeedge with one Fe(4)O5 trigonal bipyramid. In the second Fe site, Fe(2) is bonded to one O(4), one O(6), one O(8), and two equivalent O(3) atoms to form distorted FeO5 trigonal bipyramids that share corners with two equivalent Fe(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, corners with three equivalent P(3)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, and  an edgeedge with one Fe(4)O5 trigonal bipyramid.

The corner-sharing octahedral tilt angles are 48°. In the second P site, P(2) is bonded to one O(5), one O(9), and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Fe(1)O6 octahedra.

In the first O site, O(1) is bonded in a 3-coordinate geometry to one Fe(1), one Fe(4), and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Fe(3) and one P(2) atom.
