According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point charges consisting of the ligands. … http://www.cchem.berkeley.edu/rsgrp/groupsheets/d-orbitalsplitting.pdf WebThe size of the crystal field splitting only influences the arrangement of electrons when there is a choice between pairing electrons and filling the higher-energy orbitals. ...

"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. " - Crystal field splitting in tetrahedral
