The material structure described by Na2ZnGeO4 is beta beryllia-derived structured and crystallizes in the monoclinic Pc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form NaO4 tetrahedra that share corners with four equivalent Na(2)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. In the second Na site, Na(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form NaO4 tetrahedra that share corners with four equivalent Na(1)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent Na(1)O4 tetrahedra, corners with four equivalent Na(2)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 tetrahedra that share corners with four equivalent Na(1)O4 tetrahedra, corners with four equivalent Na(2)O4 tetrahedra, and corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), one Na(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing ONa2ZnGe tetrahedra. In the second O site, O(2) is bonded to one Na(1), one Na(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing ONa2ZnGe tetrahedra. In the third O site, O(3) is bonded to one Na(1), one Na(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing ONa2ZnGe tetrahedra. In the fourth O site, O(4) is bonded to one Na(1), one Na(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing ONa2ZnGe tetrahedra. is represented by the CIF file [CIF]
