The material structure described by WFeP2O8 crystallizes in the monoclinic P2_1/m space group. W(1) is bonded to one O(1), one O(3), two equivalent O(5), and two equivalent O(6) atoms to form WO6 octahedra that share corners with four equivalent Fe(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-54°. Fe(1) is bonded to one O(2), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted FeO6 octahedra that share corners with four equivalent W(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-54°. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), and two equivalent O(5) atoms to form PO4 tetrahedra that share  a cornercorner with one Fe(1)O6 octahedra, corners with three equivalent W(1)O6 octahedra, and  an edgeedge with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-52°. In the second P site, P(2) is bonded to one O(3), one O(4), and two equivalent O(6) atoms to form PO4 tetrahedra that share  a cornercorner with one W(1)O6 octahedra, corners with three equivalent Fe(1)O6 octahedra, and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-61°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Fe(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Fe(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one W(1), one Fe(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one W(1), one Fe(1), and one P(2) atom. is represented by the CIF file [CIF]
