Question

Which of The following coordination compounds has bridging carbonyl ligand?

• A. \([Mn_2(CO)_{10}]\)
• B. \([Co_2(CO)_8]\)
• C. \([Cr(CO)_6]\)
• D. \([Fe(CO)_5]\)

Answer 1

The Correct Option is B

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): \([Co_2(CO)_8]\)
