Given,The coordination complex:[ Fe(CN)6 ] 4- In octahedral complexes, d-orbitals splitting into t2g ( dxy, dyz, dzx ) and eg ( dx2-y2 , dz2 ) and we know that splitting is dependent on the strength of ligand.If the ligand is strong, then splitting will be high, so the energy gap between the two levels is more So, pairing of electrons will take place in lower energy orbital t2g first. If the ligand is weak, then the energy gap will be less between energy levels, so the pairing is not preferred. In this complexes , all the d-orbitals filled with one electron first, after that they are paired.Now, in case of [ Fe(CN)6 ] 4- :For ionic compounds, the total oxidation number of the complex is equal to ionic charge.Oxidation state of CN = -1oxidation state of Fe = x x + ( -6) = -4 x = -4 + 6 = +2The oxidation state of Fe = +2the electronic configuration of Fe2+ is : [ Ar ] 3d 6 4s0 . The electronic configuration of Fe2+ is : [ Ar ] 3d 6 4s0 In the complex, CN- is a strong field ligand so ground state energy level orbitals t2g ( dxy, dyz, dzx ) are completely filled with 6 valence electrons and there are no electrons in eg ( dx2-y2 , dz2 ) orbitals. Thus, the diagram is :Ans;)

Coordination Chemistry

It is a part of chemistry, in which the study of compounds that have central atoms surrounded by molecules or ions, known as ligand, is known as coordination chemistry.

Question

The energies of the valence \(d\) orbitals on the iron atom in the octahedral \([\text{Fe(CN)}_6]^{4-}\) complex are split according to the electron box level diagram below.

(Note: the \(d\) orbitals are labeled with just their subscript, to make the labels easier to read.)

Complete the diagram by adding the correct number of electrons to each orbital.

**Diagram Explanation:**

The diagram consists of five boxes, each representing a \(d\) orbital. The orbitals are split into two groups according to their energy levels.

- **Top row (higher energy):**
- Two boxes labeled \(z^2\) and \(x^2-y^2\).

- **Bottom row (lower energy):**
- Three boxes labeled \(xy\), \(yz\), and \(xz\).

**Instructions:**

- Use the tools provided to add electrons (\(↑↓\)) to each box, based on the electron configuration needed for the complex.

- A button is present for adding a single electron (\(↑\)), another for removing it (\(\uparrow\) with an eraser symbol), a reset button, and a submission button to finalize your configuration.
