The material structure described by ZnSn2O5 crystallizes in the orthorhombic Cmcm space group. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Sn(1) is bonded to one O(1), two equivalent O(3), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 34-51°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1) and two equivalent Sn(1) atoms to form distorted OZn2Sn2 tetrahedra that share corners with two equivalent O(1)Zn2Sn2 tetrahedra, corners with two equivalent O(2)ZnSn3 trigonal pyramids, and edges with four equivalent O(2)ZnSn3 trigonal pyramids. In the second O site, O(2) is bonded to one Zn(1) and three equivalent Sn(1) atoms to form OZnSn3 trigonal pyramids that share  a cornercorner with one O(1)Zn2Sn2 tetrahedra, corners with three equivalent O(2)ZnSn3 trigonal pyramids, edges with two equivalent O(1)Zn2Sn2 tetrahedra, and edges with two equivalent O(2)ZnSn3 trigonal pyramids. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Zn(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
