The structure described by Fe2Zn2O5 crystallizes in the orthorhombic Pbam space group. Fe(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form FeO4 tetrahedra that share corners with three equivalent Fe(1)O4 tetrahedra and corners with six equivalent Zn(1)O4 tetrahedra. Zn(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra, corners with six equivalent Fe(1)O4 tetrahedra, and  an edgeedge with one Zn(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Fe(1) and two equivalent Zn(1) atoms. In the third O site, O(3) is bonded to two equivalent Fe(1) and two equivalent Zn(1) atoms to form a mixture of edge and corner-sharing OZn2Fe2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
