The crystal structure described by (Fe4As3O16)2(O2)7 crystallizes in the cubic P-43m space group. The structure consists of seven water atoms inside a Fe4As3O16 framework. In the Fe4As3O16 framework, Fe(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form FeO6 octahedra that share corners with three equivalent As(1)O4 tetrahedra and edges with three equivalent Fe(1)O6 octahedra. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Fe(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Fe(1) and one As(1) atom. is represented by the CIF card [CIF]
