in complex ions like [CrCl4]- are the ligands covalently bonded to the cation?

Asking because they are both ions so normally it should be ionic bond.

Bonds are neither fully ionic nor fully covalent.

They are dative covalent bonds right?
Transition metal compounds are confusing, as no two are the same, they're a mix of both ionic and covalent, but formally it is dative as both electrons come from the chloride anion.

Thank you :smile:
Hi there, i can see where youre coming from, they are both ions. But they are coordinately/ datively bonded. Because if the look up the difinition for ligand, it is a species that can donate a lone pair of electrons to a transition metal ion to form a coordinate bond. Hope this helps :smile:
