The nature of the crystal field influences the pattern of splitting in d orbitals, as the asymmetry created by ligands results in distinct energy levels for the orbitals in coordination complexes.
What determines the pattern of splitting in the d orbitals when subjected to different crystal fields?

The pattern of splitting in d orbitals when subjected to different crystal fields is determined by the orientation of the ligands around the metal ion. In an octahedral crystal field, where ligands surround the metal ion along the axes, the d orbitals split into higher-energy eg and lower-energy t₂g sets. In a tetrahedral crystal field, where ligands approach from the corners of a tetrahedron, the splitting pattern is different. The nature of the crystal field, whether octahedral or tetrahedral, influences the extent of repulsion between metal and ligand electrons, resulting in distinct energy levels for the d orbitals in coordination complexes.
