Central atom?

Postby KNguyen_1I » Sun Nov 24, 2019 6:56 pm

Does the central atom of a coordination compound *have* to be a transition metal or can they include alkali/alkali-earth metals as well?
Also, what are the formal stipulations for a compound to be considered a coordination compound and are the ligands always ionically bonded to a metal central atom?

Yes, a coordination compound is a transition metal bonded to ligands, specifically by coordinate covalent bonds, in which the ligand donates both e- from a lone pair

Okay, that makes sense

Does it have something to do with the electrons used for the bond being from d-orbitals, the fact that it’s only transition metals? I had OP’s question as well.

Yes it has to be transition metals

Yes, only transition metals can be the central atom.
