Expert Answer:

The ? splitting energy for tetrahedral metal complexes (four ligands),  is smaller than that for an octahedral complex. Therefore, it is rare to have a ? large enough to cause electrons to pair before filling high orbitals. Thus, tetrahedral complexes are usually high-spin. "There are no known ligands which are powerful enough to produce the strong-field case in a tetrahedral complex.
