ZnSb2O5 crystallizes in the orthorhombic Cmcm space group. Zn(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form corner-sharing ZnO4 tetrahedra. Sb(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), and three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1) and two equivalent Sb(1) atoms to form corner-sharing OZn2Sb2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one Sb(1) atom.
ZnSb2O5 crystallizes in the orthorhombic Cmcm space group. Zn(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form corner-sharing ZnO4 tetrahedra. Both Zn(1)-O(1) bond lengths are 2.31 Å. Both Zn(1)-O(3) bond lengths are 1.92 Å. Sb(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), and three equivalent O(2) atoms. The Sb(1)-O(1) bond length is 2.13 Å. The Sb(1)-O(3) bond length is 1.88 Å. There are two shorter (2.07 Å) and one longer (2.57 Å) Sb(1)-O(2) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1) and two equivalent Sb(1) atoms to form corner-sharing OZn2Sb2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one Sb(1) atom.
