Copper sulfates and selenates, quantum magnets exhibiting magnetic spin 1/2 copper sites, show a large variety of crystal structures depending on the amount of crystal water, ranging from water free compounds to up to five water molecules per Cu spin. The different amount of crystal water has a surprisingly strong influence on the magnetic properties of the different species. Here, we present a detailed study of the structure property relation for this compound family based on microscopic grounds.
