The material described by Sb2O7 crystallizes in the orthorhombic Ima2 space group. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 44-45°. In the second Sb site, Sb(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 44-46°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Sb(2) and one O(5) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one O(1) atom. is represented by the CIF file [CIF]
