ZnSb3O7 is Antimony trioxide-derived structured and crystallizes in the orthorhombic Pnma space group. Zn(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(4) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. In the second Sb site, Sb(2) is bonded in a distorted trigonal bipyramidal geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one Sb(2) atom. In the second O site, O(4) is bonded in a distorted trigonal planar geometry to one Zn(1) and two equivalent Sb(1) atoms. In the third O site, O(1) is bonded in a 4-coordinate geometry to one Zn(1), one Sb(2), and two equivalent Sb(1) atoms. In the fourth O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Sb(2) and two equivalent Sb(1) atoms.
