Explanation:

Step 1:
First, we need to identify the central metal atom in the molecule. Here, it is Molybdenum (Mo).

Step 2:
Next, we need to identify the ligands attached to the central metal atom. Here, the ligands are Cp (Cyclopentadienyl) and CO (Carbon Monoxide).

Step 3:
The coordination number of Mo in the given molecule is 6. This is because there are 2 CO ligands and 1 Cp ligand attached to each Mo atom.

Step 4:
Now, we need to count the number of metal-metal bonds in the molecule. In [CpMo(CO)2]2, there are two Mo atoms connected by a single bond. Therefore, there is one metal-metal bond in each molecule.

Step 5:
However, we need to consider the fact that there are two molecules of [CpMo(CO)2]2 in the given compound. Therefore, we need to count the number of metal-metal bonds in both molecules.

Final Answer:
There is one metal-metal bond in each molecule of [CpMo(CO)2]2. Since there are two molecules in the compound, the total number of metal-metal bonds is 2 x 1 = 2. However, we need to count the shared bond between the two molecules, which gives us a total of 3 metal-metal bonds.
