Zn(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are two inequivalent Ge sites.

In the third O site, O(1) is bonded in a 3-coordinate geometry to one Zn(1) and two equivalent Ge(2) atoms. In the fourth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and two equivalent Ge(1) atoms. In the fifth O site, O(3) is bonded in a distorted T-shaped geometry to one V(1), one Zn(1), and one Ge(2) atom.
