**Topic: Determining the Central Atom Valence Orbitals' Irreducible Representations in a Square Base Pyramidal [CuCl₅]³⁻ Complex**

**Introduction**

Consider the square base pyramidal [CuCl₅]³⁻ complex. Using the provided reference system and with the knowledge that its point group is \( C_{4v} \), analyze and answer the following questions related to the valence orbitals of the central atom.

**Molecular Geometry Representation**

*Diagram Description:*
The diagram illustrates the [CuCl₅]³⁻ complex in a 3D configuration. Central to the structure is a copper (Cu) atom, with chlorine (Cl) atoms positioned in a square pyramidal arrangement.

- The copper atom is at the center, depicted as "Cu".
- Chlorine atoms are labeled as "Cl" at various positions.
- The axes are denoted: \( x \) points horizontally, \( y \) points diagonally, and \( z \) points vertically.

This diagram effectively represents the 3D molecular geometry to aid in understanding the orbital interactions.

**Task**

a. **Determine the Central Atom Valence Orbitals' Irreducible Representations**

Use symmetry analysis and group theory principles to determine how the valence orbitals of the copper atom transform under the symmetry operations of the \( C_{4v} \) point group.

**Conclusion**

Examine the diagram and apply symmetry considerations to classify the copper atom's valence orbitals. Identify the irreducible representations that describe their behavior under the point group operations. This information is crucial for understanding the electronic structure and bonding characteristics of the complex.
