Here is your answer ⤵⤵⤵

In CuSO4.5H2O, Cu is cordinated with 4 water molecules and two more oxygen atoms fron Sulphate ion.

Now fifth water molecule is hydrogen bonded and is deeply embedded in crystal. It is not cordinated.

Only 4 water molecules are coordinated and fifth is only hydrogen bonded.
