How do transition elements form coordination compounds?
Transition metal ions are highly Lewis-acidic........
Transition metal ions are highly Lewis acidic, and we can typically observe
In the presence of other ligands, i.e. other Lewis bases such as
As with all chemical reactions, both charge and mass are conserved, so with neutral ligands (such as water above), the charge of the metal ion is preserved, and to isolate this material as a pure substance we would have to introduce a counterion of some sort to give, for instance,
Anyway, there is not much more I can say without leading you down the garden path. You have lecture notes and a text book, which will say the same thing I have said here in detail, and much more eloquently. Read them!
