FeSbO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with eight equivalent Sb(1)O6 octahedra and edges with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with eight equivalent Fe(1)O6 octahedra and edges with two equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Fe(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Fe(1) and two equivalent Sb(1) atoms.
