Crystal field theory and ligand field theory

WebDec 29, 2024 · According to the crystal field theory, the metal ion is surrounded by an electric field created by the ligands. In a complex, the attraction between the core metal and the ligand is solely electrostatic. The metal ion is targeted by the negative end of the dipole of the neutral molecule ligand. WebCrystal Field Theory. T. o explain the observed behavior of transition metal complexes (such as. how colors arise), a model involving electrostatic interactions between the. electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory ...
