Question

Answer

The IUPAC name of the complex [(CO)5Mn - Mn(CO)5] is bis(pentacarbonyldimanganese). Let's break down the name and understand it in detail.

1. Complex Formula:
The complex [(CO)5Mn - Mn(CO)5] consists of two manganese atoms bonded together, with each manganese atom surrounded by five carbon monoxide (CO) ligands. The central Mn atom is connected to one Mn atom through a single bond.

2. Naming the Central Atom:
The central atom is manganese (Mn). Since there is only one central atom, we use the prefix 'bis' to indicate two separate Mn atoms.

3. Naming the Ligands:
The ligands in this complex are carbon monoxide (CO). Each Mn atom is surrounded by five CO ligands. The prefix 'pentacarbonyl' is used to indicate the presence of five CO ligands.

4. Naming the Complex:
Putting it all together, the IUPAC name of the complex is 'bis(pentacarbonyldimanganese).' This name indicates that there are two manganese atoms bonded together, with each Mn atom coordinated to five CO ligands.

In summary, the IUPAC name 'bis(pentacarbonyldimanganese)' accurately describes the composition of the complex [(CO)5Mn - Mn(CO)5]. The central Mn atom is bonded to another Mn atom through a single bond, and each Mn atom is coordinated to five CO ligands.

Answer

Deca is used when there 10 ligands are present. Since Manganese is 2 here that's why it is dimanganate.
One thing more, ate is used in manganate because it is an anionic complex
