    The EAN of each Mn (Z = 25) in its carbonyl compound is 36. What is the structure of the carbonyl compound with molecular formula \[M{{n}_{2}}{{(CO)}_{10}}\]? 

    Answer:

                    EAN = Atomic no. (Z) of Mn atom + 2 CN + Electron from Mn-Mn bond. = 25 + 2 x 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:
