Hexa-aquo complexes
Most aquo complexes are mono-nuclear, with the general formula [M(H2O)6], with n = 2 or 3; they have an octahedral structure. The water molecules function as Lewis bases, donating a pair of electrons to the metal ion and forming a dative covalent bond with it. Typical examples are listed in the following table.
