# Introduction to Crystal Field Splitting## 5. Crystal Field Splitting QuestionsThis section explores concepts related to crystal field splitting in coordination complexes.### A. Octahedral Complex Crystal Field Splitting- **Task**: Draw the crystal field splitting diagrams for both high spin and low spin \(d^5\) complexes. - **Requirements**: - Correctly label symmetry labels for orbitals. - Identify the number of unpaired electrons for each diagram.### B. Square Base Pyramidal [CuCl\(_3\)]\(^3-\) Complex#### Structure and Symmetry- **Diagram Explanation**: - The diagram represents a [CuCl\(_3\)]\(^3-\) complex with a square base pyramidal geometry. - The coordinate system is provided with the \(z\)-axis pointing upwards, indicating a chlorine ligand atop copper. - Four chlorine ligands are positioned in a square planar arrangement perpendicular to the \(z\)-axis, with copper at the center.#### Questions- **Oxidation State**: - Determine the oxidation states of copper (Cu) and chlorine (Cl) in the given complex.### C. Crystal Field Splitting for [CuCl\(_3\)]\(^3-\)- **Task**: Create the crystal field splitting diagram for the complex.- **Assumptions**: - Each ligand acts as a point charge. - The extent of overlap with copper's d-orbitals determines energy levels.- **Requirements**: - Label the energy scale. - Correctly position d-orbitals according to their energy levels. - Assign each d-orbital its proper symmetry label. - Fill in the correct number of electrons for each orbital.By completing these sections, students will gain a deeper understanding of how crystal fields influence electron configurations and properties in coordination complexes.
