SbO4 is Upper Bainite-like structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional and consists of eight water molecules and one SbO3 framework. In the SbO3 framework, there are two inequivalent Sb sites. In the first Sb site, Sb is bonded to six O atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 46°. There is two shorter (1.99 Å) and four longer (2.00 Å) Sb–O bond length. In the second Sb site, Sb is bonded to six O atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 45–46°. All Sb–O bond lengths are 2.00 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to two Sb atoms. In the second O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent Sb atoms. In the third O site, O is bonded in a bent 150 degrees geometry to two equivalent Sb atoms.
