The material structure described by ZnSn2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted ZnO6 octahedra that share corners with six equivalent Sn(1)O4 tetrahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent Sn(2)O6 octahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SnO4 tetrahedra that share corners with six equivalent Zn(1)O6 octahedra and corners with six equivalent Sn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-74°. In the second Sn site, Sn(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Sn(1)O4 tetrahedra, edges with two equivalent Sn(2)O6 octahedra, and edges with four equivalent Zn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1), one Sn(1), and one Sn(2) atom to form distorted OZn2Sn2 trigonal pyramids that share corners with six equivalent O(2)ZnSn3 tetrahedra, corners with six equivalent O(1)Zn2Sn2 trigonal pyramids, edges with two equivalent O(2)ZnSn3 tetrahedra, and  an edgeedge with one O(1)Zn2Sn2 trigonal pyramid. In the second O site, O(2) is bonded to one Zn(1), one Sn(1), and two equivalent Sn(2) atoms to form OZnSn3 tetrahedra that share corners with six equivalent O(2)ZnSn3 tetrahedra, corners with six equivalent O(1)Zn2Sn2 trigonal pyramids,  an edgeedge with one O(2)ZnSn3 tetrahedra, and edges with two equivalent O(1)Zn2Sn2 trigonal pyramids. is represented by the CIF file [CIF]
