Question

What do you mean by the term hapticity of an organic ligand? Give an example to demonostrate multiple hapticity of same ligand in different organometallic compounds?

Answer 1

Hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. The hapticity of a ligand is described with the Greek letter η ('eta'). For example, η2 describes a ligand that coordinates through 2 contiguous atoms.
