The EAN of each Mn(Z=25) in its carbonyl compound is 36. What is the structure of the carbonyl compound with molecular formula `Mn_(2)(CO_(10))`?

Text Solution

Verified by Experts

EAN = Atomic no. (Z) of Mn atom + 2 CN + Electron from Mn-Mn bond. `= 25+ 2 xx 5+1=36`
In the complex, five CO ligands are co-ordinated to each Mn atom and the sixth co-ordination number is attained by other Mn atom of Mn-Mn bond. The structure of the complex is:
