The crystal structure described by (Fe3Zn2As3O17)2(O2)9 crystallizes in the monoclinic Cm space group. The structure consists of six 7782-44-7 molecules and two trioxidane molecules inside a Fe3Zn2As3O17 framework. In the Fe3Zn2As3O17 framework, there are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(2), one O(8), two equivalent O(10), and two equivalent O(6) atoms to form FeO6 octahedra that share  a cornercorner with one As(1)O4 tetrahedra, corners with two equivalent As(2)O4 tetrahedra, edges with two equivalent Fe(2)O6 octahedra, and  an edgeedge with one Zn(1)O5 trigonal bipyramid. In the second Fe site, Fe(2) is bonded to one O(10), 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 As(1)O4 tetrahedra, corners with two equivalent As(2)O4 tetrahedra,  an edgeedge with one Fe(1)O6 octahedra,  an edgeedge with one Fe(2)O6 octahedra, and  an edgeedge with one Zn(1)O5 trigonal bipyramid. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(9), two equivalent O(10), and two equivalent O(7) atoms to form distorted ZnO5 trigonal bipyramids that share corners with two equivalent As(2)O4 tetrahedra,  an edgeedge with one Fe(1)O6 octahedra, and edges with two equivalent Fe(2)O6 octahedra. In the second Zn site, Zn(2) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(12), and two equivalent O(6) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form AsO4 tetrahedra that share  a cornercorner with one Fe(1)O6 octahedra and corners with two equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-53°. In the second As site, As(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form AsO4 tetrahedra that share  a cornercorner with one Fe(1)O6 octahedra, corners with two equivalent Fe(2)O6 octahedra, and  a cornercorner with one Zn(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 48-54°. There are eleven inequivalent O sites. In the first O site, O(12) is bonded in a single-bond geometry to one Zn(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(2) and one As(1) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to one Fe(1) and one As(1) atom. In the fourth O site, O(3) is bonded in a bent 120 degrees geometry to one Fe(2) and one As(1) atom. In the fifth O site, O(4) is bonded in a bent 120 degrees geometry to one Fe(2) and one As(2) atom. In the sixth O site, O(5) is bonded in a bent 120 degrees geometry to one Fe(2) and one As(2) atom. In the seventh O site, O(6) is bonded in a distorted trigonal planar geometry to one Fe(1), one Zn(2), and one As(2) atom. In the eighth O site, O(7) is bonded in a bent 120 degrees geometry to one Zn(1) and one As(2) atom. In the ninth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to one Fe(1) and two equivalent Fe(2) atoms. In the tenth O site, O(9) is bonded in a trigonal non-coplanar geometry to two equivalent Fe(2) and one Zn(1) atom. In the eleventh O site, O(10) is bonded in a distorted trigonal non-coplanar geometry to one Fe(1), one Fe(2), and one Zn(1) atom. is represented by the CIF file [CIF]
