Question

What are metal carbonyls? Explain with examples.

✓

Answer

→ "A complex of transition metal with carbon monoxide (Carbonyl ligand) are known as metal carbonyls."
\begin{aligned}→ Example : \left[ Ni ( CO )_4\right] & \ \ Tetranedral \\ {\left[ Fe ( CO )_5\right] } &\ \ Trigonal bipyramidal \\ {\left[ Cr ( CO )_6\right] } &\ \ Octahedral \end{aligned}
→ Decacarbonyldimanganese (O) is made up of two square pyramidal $Mn ( CO )_5$ units joined by a Mn - Mn bond. Octacarbonyldicobalt(O) has a Co - Co bond bridged by two CO groups.
