Which of The following coordination compounds has bridging carbonyl ligand?
- \([Mn_2(CO)_{10}]\)
- \([Co_2(CO)_8]\)
- \([Cr(CO)_6]\)
- \([Fe(CO)_5]\)
The Correct Option is B
Solution and Explanation
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): \([Co_2(CO)_8]\)
