According to the crystal field theory,
JAHN TALLER DISTORTION- According to it, If any metal posses Electronic degeneracy in Octahedral field then it will try to remove its electronic energy by lowering the overall symmetry of the molecule.
Z- OUT DISTORTION/ AXIAL ELONGATION - the energies of d- Orbitals having Z factor i.e. dxz, dyz, dz2. are lowered and the bonds along Z- axis elongates.
this type of distortion generally occurred with degenerate eg level.
Z-IN DISTORTION / AXIALLY COMPRESSED / TETRAGONALY COMPRESSED - the energies of d- orbitals with Z factor i.e.. dxz, dyz, dz2 , increased and the bond along Z- axis compressed or shortened.
Using the crystal field theory approach, draw the d-orbital splitting diagram for octahedral [Cu(...

2.) Starting with the octahedral (ML6) crystal field splitting pattern below: A.) Draw the d-orbital splitting for a tetragonally compressed compound (ML6). This is where the ligands along the z-axis are pushed closer to the metal center, and the ligands along the x and y-axis are pulled further from the metal center (10 marks). B.) Continue this trend until the ligands along the x and y axes are completely removed, and show the d-orbital splitting for the resulting linear complex...

-Drawing a crystal field theory energy level diagram Using crystal field theory, draw an electron box energy level diagram for the valence d orbitals on the vanadium atom in a complex. Your diagram should show the relative energy of each orbital, and the number of electrons in each orbital. Note: to make your diagram easier to read, label the d orbitals with just the subscript. For example, label the d.2 orbital with just z energy
