Correct Answer: 0

Solution and Explanation

In \(\mathrm{Mn_2(CO)_{10}}\) each Mn is bonded to five terminal CO groups (in an octahedral arrangement) and to the other Mn through a metal-metal bond.
The structure is \(\mathrm{(OC)_5Mn-Mn(CO)_5}\); there are no CO groups bridging the two metal atoms.
Number of bridging CO ligands = 0.
