Cuprates show an intimate interplay between the crystal structure and their magnetism, particularly with respect to frustration and dimensionality. On the other hand, it is a widespread belief that crystal water has just a moderate and quantitative influence to the magnetic properties of these compounds caused by the modification of interatomic distances. In contrast, the hydration of CuCl2 leads to a dramatic change in magnetic behaviour and ground state. While CuCl2·2H2O is a classic example for a three-dimensional antiferromagnet (TN 4.3 K) [1] with small exchange couplings, CuCl2 is a quasi-one dimensional chain compound that exhibits long-range order at T 24 K [2].
