Question

Multi·dentate phosphine ligands are often notated with this Greek letter followed by the number of coordination sites they have. For 10 points each:
[10h] Name this Greek letter that is used to denote the denticity of ligands, or how many non-contiguous binding sites they have. Acetate ligands can be described as “[this letter]-2.”
ANSWER: kappa
[10m] While denticity describes non-contiguous binding sites, this other quantity denoted with the Greek letter eta describes the number of binding sites that are contiguous. Cyclo·penta·diene ligands have a value of five for this quantity.
ANSWER: hapticity
[10e] Two eta-five cyclo·penta·diene ligands are bound to an iron(II) (“iron-two”) center in this classic sandwich compound, the first-discovered metallocene.
ANSWER: ferrocene [accept Fc]
