The structure described by CoZn(GeO3)2 is Esseneite structured and crystallizes in the triclinic P-1 space group. Co(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form CoO6 octahedra that share corners with three equivalent Ge(1)O4 tetrahedra, corners with three equivalent Ge(2)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. Zn(1) is bonded in a rectangular see-saw-like geometry to one O(3), one O(4), one O(5), and one O(6) atom. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form GeO4 tetrahedra that share corners with three equivalent Co(1)O6 octahedra and corners with two equivalent Ge(2)O4 tetrahedra.

The corner-sharing octahedral tilt angles range from 50-59°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Co(1), one Zn(1), and one Ge(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Co(1), one Zn(1), and one Ge(1) atom.
