WebAug 13, 2024 · Tetrahedral complexes have four ligands on the apexes of a tetrahedron around the central metal. [CoX 4] 2- (X = Cl, Br, I), Ni (CO) 4, etc. are all examples of 4-coordination complexes (Figure 6.2.5 ). WebAug 15, 2024 · An example of the tetrahedral molecule CH 4, or methane. In a tetrahedral complex, Δ t is relatively small even with strong-field ligands as there are fewer ligands to bond with. It is rare for the Δ t of tetrahedral complexes to exceed the pairing energy. Usually, electrons will move up to the higher energy orbitals rather than pair.
