Re: Why can CO3(2-) be a mono/bidentate ligand
Normally Carbonate is monodentate, because it only has 120 degrees between its Oxygens, so two oxygens cannot bind to the same metal. However, in some cases carbonate bonds to two different metals, making it bidentate.

Re: Why can CO3(2-) be a mono/bidentate ligand
Are there any other examples of ligands like CO3^2- that are both monodentate and bidentate (depending on the size of the central metal atom)?
NO2- and SO4^2-, which, like CO3^2-, have several oxygens available for binding, are both monodentate only.
Is this because NO2- has a bond angle of <120 & SO4^2- has a bond angle of 109.5?
Is 120 degrees the cutoff for being able to act as a monodentate and bidentate ligand?

If it is bonding to two different metals, then isn't it not a coordination compound? i thought the denticity was when they "bite" onto the same atom
