Do we call metal carbonyls as organometallics?

Answer

To determine whether metal carbonyls can be classified as organometallic compounds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Metal Carbonyls**:
- Metal carbonyls are compounds that consist of a metal atom bonded to carbon monoxide (CO) ligands. The general formula for metal carbonyls can be represented as M(CO)n, where M is the metal and n is the number of CO ligands attached to it.

2. **Definition of Organometallic Compounds**:
- Organometallic compounds are defined as compounds that contain at least one bond between a carbon atom of an organic group and a metal atom. This means that the presence of a carbon atom directly bonded to a metal is a key characteristic of organometallics.

3. **Bonding in Metal Carbonyls**:
- In metal carbonyls, the carbon atom of the CO ligand is indeed bonded to the metal atom. This bond can be described as having both sigma (σ) and pi (π) character. The sigma bond is formed by the overlap of the metal's d-orbitals with the carbon's p-orbital, while the pi bond arises from the back-donation of electron density from the metal to the empty π* orbitals of CO.

4. **Conclusion**:
- Since metal carbonyls contain a carbon atom that is directly bonded to a metal atom, they fulfill the criteria for organometallic compounds. Therefore, we can conclude that metal carbonyls are indeed classified as organometallics.

### Final Answer:
Yes, metal carbonyls are called organometallics.
