Hydrated crystals
Crystals of hydrated copper(II) sulfate consist of [Cu(H 2 O) 4] 2+ centers linked to SO 2− 4 ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water. A fifth water resides elsewhere in the framework but does not bind directly to copper.
