Crystal Field Theory: Square Planar Splitting

Crystal Field Splitting (Square Planar)

Visualizing splitting via Z-out Jahn-Teller distortion to infinity.

Square Planar Splitting: Occurs often in d⁸ complexes (e.g., Pt²⁺, Pd²⁺, Ni²⁺ strong field). It is an extreme case of removing the axial ligands from an octahedral complex.
