The coordination compound with a bridging carbonyl ligand is [Co2(CO)8].
In this compound, the cobalt atoms are bridged by carbonyl ligands, which means the carbonyl ligands are shared between the two cobalt atoms, forming a bridging structure.
From structure it is clear [Co2(CO)8] has bridging carbonyl ligand.

So, the Correct option is (B): \([Co_2(CO)_8]\)
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

There are three applications of coordination compounds:
