In which one of the following metal carbonyls, CO forms a bridge between metal atoms?
Options
- ACo 2 ( CO ) 8
- BMn 2 ( CO ) 10
- COs 3 ( CO ) 12
- DRu 3 ( CO ) 12
Correct answer
A. Co 2 ( CO ) 8
Step-by-step solution
In the most common bridging mode, denoted μ 2 or simply μ , the CO ligand bridges a pair of metals. This bonding mode is observed in the commonly available metal carbonyls: Co 2 CO 8 , Fe 2 CO 9 , Fe 3 CO 12 and Co 4 CO 12 . In certain higher nuclearity clusters, CO bridges between three or even four metals.
