The crystalline copper(2) sulphate, CuSO4 5H2O has the structure in which four water molecules are coordinated to the central copper cation in square planar structure. The fifth water molecule is held by hydrogen bonds between a sulphate anion and a coordinated water molecule. The fifth hydrogen bonded water molecule is deeply embedded in the crystal lattice and hence not easily removed.505-162_CuSO4.5H2O.PNG

Hey student..
In CuSO4.5H2O, four water molecules are coordinated to Cu+2, while one is hydrogen bonded with SO42-.
Copper sulfate pentahydrate contains copper(II) in a geometry best described as distortedoctahedral. The copper(II) is bound to four water molecules in a square-planar geometryand two oxygen atoms from two sulfate ions (one H2O is H-Bonded here).
This salt dissolves in water to produce thepale-blue [Cu(H2O)6]2+ion, in which two of the water molecules are less tightly held andhave longer bond distances.
