The structure described by Zn2Sn3O8 crystallizes in the monoclinic C2/m space group. Zn(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(3) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form edge-sharing SnO6 octahedra. In the second Sn site, Sn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing SnO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Zn(1) and two equivalent Sn(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Sn(1) and two equivalent Sn(2) atoms. In the third O site, O(3) is bonded to two equivalent Zn(1), one Sn(1), and one Sn(2) atom to form a mixture of distorted corner and edge-sharing OZn2Sn2 trigonal pyramids. is represented by the CIF file [CIF]
