These complexes may be homoleptic, that is containing only CO ligands, such as nickel carbonyl (Ni(CO)4), but more commonly metal carbonyls are heteroleptic and contain a mixture of ligands. Mononuclear metal carbonyls contain only one metal atom as the central atom.

Generally Mn gives [Mn2(CO)10]Fe gives [Fe(CO)5], [Fe2(CO)9], [Fe3(CO)12 ] And Co gives [Co2(CO)8 ] ,[Co4 (CO)12 ] But Cr do not gives such type of carbonyl complex.. So its won't give homoleptic polynuclear complex but yes it will give hetroleptic polynuclear complex

Amongst the following, the metal that does not form homoleptic polynuc...
Metal Carbonyls

Metal carbonyls are coordination complexes that contain carbon monoxide (CO) as a ligand. They are known for their stability and volatility, as well as their ability to form homoleptic polynuclear metal carbonyls, meaning that all ligands are carbon monoxide.

Homoleptic Polynuclear Metal Carbonyls

Homoleptic polynuclear metal carbonyls are coordination complexes that contain only carbon monoxide as a ligand. They are known for their high stability and volatility, as well as their ability to form metal-metal bonds within the complex.

Metal that does not form homoleptic polynuclear metal carbonyl

Amongst the given options, the metal that does not form homoleptic polynuclear metal carbonyl is Cr (Chromium). Chromium is known for its ability to form heteroleptic polynuclear metal carbonyls, meaning that it can form complexes that contain both carbon monoxide and other ligands.

Conclusion

In conclusion, the correct answer is option 'C' (Cr), because it is the only metal amongst the given options that does not form homoleptic polynuclear metal carbonyls.
