The structure described by ZnSn(GeO3)2 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Zn(1) is bonded in a see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Sn(1) is bonded in a see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form corner-sharing GeO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Zn(1), one Sn(1), and one Ge(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 Ge(1) atom. is represented by the CIF card [CIF]
