Single crystals of a new aqua­hydroxido­copper(II) oxovanadium(IV) vanadate have been synthesized hydro­thermally at 473 K. The three-dimensional structure presents layers of vanadate tetrahedra and distorted oxovanadium octahedra connected by Cu atoms.

Zn2(TeO3)Cl2 has a layered structure in which the Cl atoms and the 5s2 lone pairs of the TeIV atom protrude from the surfaces of each layer towards adjacent layers, which are only held together by dispersion forces. The compound is isostructural with the synthetic compound CuZn(TeO3)Cl2 and the mineral sophiite, Zn2(SeO3)Cl2.
