Question 46

The coordination geometry around the manganese in decacarbonyldimanganese(0) is:

Decacarbonyldimanganese(0) is Mn$$_2$$(CO)$$_{10}$$.

Each Mn is bonded to 5 CO ligands and one Mn-Mn bond, giving 6 groups around each Mn.

This corresponds to octahedral geometry.

The answer is Option (1): Octahedral.
