Understanding the Organometallic Compounds
Organometallic compounds can exhibit different types of bonding interactions, primarily σ (sigma) and π (pi) bonding. In the context of the given options, let’s examine why option D is the correct answer.
σ and π Bonding in Organometallics
- σ Bonding: This occurs when there is a head-on overlap of orbitals, allowing for the formation of a strong bond between the metal and the ligand.
- π Bonding: This type of bonding involves the side-on overlap of p-orbitals, where the ligands donate electron density into empty d-orbitals of the metal.
Analysis of Each Option
- a) [Fe (η5 – C5H5)2]: This compound features cyclopentadienyl ligands which primarily engage in σ bonding through their lone pairs. However, the π bonding is not as prominent as in other complexes.
- b) Fe (CH3)3: Methyl groups are primarily σ donors. There is no significant π bonding in this compound.
- c) K [PtCl3(η2 – C2H4)]: Ethylene (C2H4) acts as a π-acceptor ligand but does not exhibit both σ and π bonding extensively.
- d) [Co(CO)5 NH3]2+:
- The CO ligands are strong σ donors and also engage in π back-bonding with the cobalt metal center.
- NH3 is a σ donor but does not participate in π bonding.
- The presence of CO ligands allows for a combination of both σ and π interactions.
Conclusion
Therefore, option D is the only compound in this list that exhibits both σ and π bonding due to the strong back-donation capability of CO ligands along with the σ donation from NH3. This unique interaction makes it the correct choice among the options provided.
