ZnSnSi2O6 crystallizes in the monoclinic C2/c space group. Zn(1) is bonded in a distorted see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Sn(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Si(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form corner-sharing SiO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Si(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Zn(1), one Sn(1), and one Si(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Zn(1), one Sn(1), and one Si(1) atom.
