The material described by ZnSn2O4 crystallizes in the orthorhombic Pnma space group. The structure consists of four 7440-66-6 atoms inside a SnO2 framework. In the SnO2 framework, there are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to one O(4), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. In the second Sn site, Sn(2) is bonded to one O(2), two equivalent O(4), and three equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Sn(2) and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Sn(1) and two equivalent Sn(2) atoms. is represented by the CIF card [CIF]
