The structure described by ZnSn3O7 crystallizes in the orthorhombic Pnma space group. Zn(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a water-like geometry to one Zn(1) and one Sn(2) atom. In the second O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Zn(1) and two equivalent Sn(1) atoms. In the third O site, O(1) is bonded to one Zn(1), one Sn(2), and two equivalent Sn(1) atoms to form a mixture of corner and edge-sharing OZnSn3 tetrahedra. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to one Zn(1), one Sn(2), and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
