The compound described by Sb3O7 crystallizes in the orthorhombic Imma space group. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. In the second Sb site, Sb(2) is bonded to two equivalent O(4) and four equivalent O(1) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 42-49°. In the third Sb site, Sb(3) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 43-49°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Sb(1), one Sb(2), and one Sb(3) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Sb(3) atoms. In the third O site, O(3) is bonded in a bent 120 degrees geometry to two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. is represented by the CIF card [CIF]
