WebLigand field strength can also affect the geometry of transition metal complexes. An illustrative example is that of four coordinate d8 complexes. Binding to weak‐ field ligands promotes the formation of tetrahedral complexes, for example NiCl 4 2– or NiCl 2 (PPh 3) 2, whereas strong‐field ligands promote the formation of square planar WebLigand field theory was developed during the 1930s and 1940s as an extension of crystal field theory (CFT).
