Zn(SbO2)2 is Spinel-like structured and crystallizes in the trigonal R3m space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(3) and three equivalent O(4) atoms to form ZnO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-59°. In the second Zn site, Zn(2) is bonded to three equivalent O(1) and three equivalent O(4) atoms to form ZnO6 octahedra that share corners with three equivalent Zn(1)O4 tetrahedra, corners with three equivalent Sb(1)O4 trigonal pyramids, and edges with six equivalent Sb(2)O6 octahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(2) and three equivalent O(1) atoms to form SbO4 trigonal pyramids that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-69°. In the second Sb site, Sb(2) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with three equivalent Zn(1)O4 tetrahedra, corners with three equivalent Sb(1)O4 trigonal pyramids, edges with two equivalent Zn(2)O6 octahedra, and edges with four equivalent Sb(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Zn(2), one Sb(1), and two equivalent Sb(2) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Sb(1) and three equivalent Sb(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal pyramidal geometry to one Zn(1) and three equivalent Sb(2) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Zn(1), one Zn(2), and two equivalent Sb(2) atoms.
