As I showed in a previous post, even water is a ligand:

Just to clarify...

Ligands are only called ligands when they form coordinate covalent bonds with a metal ion, right? Or are they called ligands even though they form a bond with another covalent compound?
For example?

No, I just intended to try to clarify the subject a little bit (even to myself  ;)). I think that when water or another species acts as ligand, a covalent bond have to form, so, as you say, the bond of water with ions as Na+ in the solvation shoudn't be considered as coordinative, that is, those compounds shouldn't be considered as complexes.
