WebTherefore, the crystal field splitting diagram for tetrahedral complexes is the opposite of an octahedral diagram. The d x2 −d y2 and dz 2 orbitals should be equally low in energy because they exist between the ligand axis, allowing them to experience little repulsion. WebSep 10, 2024 · So there is less splitting in tetrahedral splitting as compared to the splitting of octahedral complexes. 4. Size of a metal atom. The size of the metal atom also affects crystal field splitting energy. When we move from top to bottom in a group, the crystal field splitting energy increases. This is due to the increase in the size of metal …
