Answer

To determine the IUPAC name of the complex with the formula \([CO_3Fe(CO)_3Fe(CO)_3]\), we will follow these steps:

### Step 1: Identify the Components of the Complex
The complex consists of iron (Fe) and carbonyl (CO) ligands. Each iron is coordinated to three carbonyl ligands, and there are bridging carbonyl ligands between the two iron centers.

### Step 2: Understand the Structure
The structure can be visualized as two iron centers connected by bridging carbonyl ligands. Each iron is surrounded by three carbonyl ligands.

### Step 3: Determine the Type of Ligands
- The carbonyl (CO) is a neutral ligand.
- The bridging carbonyls are represented as "μ" (mu) in the nomenclature.

### Step 4: Naming the Ligands
- Since there are three bridging carbonyl ligands, we denote this as "tri" for the three bridging ligands.
- The carbonyl ligands are named as "carbonyl".

### Step 5: Combine the Ligand Names
For the two iron centers, since they are identical, we use "bis" to indicate that there are two of them. Therefore, we will say "bis tricarbonyl" for the two iron centers.

### Step 6: Identify the Central Metal and Its Oxidation State
- The central metal is iron (Fe).
- The oxidation state of iron in this complex is zero, as it is coordinated with neutral ligands.

### Step 7: Construct the Full IUPAC Name
Putting all the components together, we get:
- The full IUPAC name is: **"tri-μ-carbonyl bis(tricarbonyl)iron(0)"**.

### Final Answer
The IUPAC name of the complex \([CO_3Fe(CO)_3Fe(CO)_3]\) is **"tri-μ-carbonyl bis(tricarbonyl)iron(0)"**.
