Question

In which one of the following metal carbonyls, CO forms a bridge between metal atoms?

$\text{[Co}_2(\text{CO})_8]$

$\text{[Mn}_2(\text{CO})_{10}]$

$\text{[Os}_3(\text{CO})_{12}]$

$\text{[Ru}_3(\text{CO})_{12}]$

Answer

$\text{[Co}_2(\text{CO})_8]$

Explanation

Solution

In [Co2(CO)8], the CO ligands form bridging bonds between the cobalt (Co) atoms. This bridging CO coordination is a characteristic feature of [Co2(CO)8], where two cobalt atoms are connected via CO ligands that act as bridges.

The structures of each option are as follows:

(1) [Co2(CO)8] - Contains bridging CO between Co atoms.
(2) [Mn2(CO)10] - No bridging CO.
(3) [Os3(CO)12] - No bridging CO.
(4) [Ru3(CO)12] - No bridging CO.

Thus, [Co2(CO)8] is the correct answer where CO forms a bridge between metal atoms.

So, the correct answer is : Option (1)
