WebCrystal Field Effects in Octahedral Complexes When the d orbitals of a metal ion are placed in an octahedral field of ligand electron pairs, directed at the surrounding ligands, are raised in energy. The d xy, d xz, and d yz orbitals, which are directed between the surrounding ions, are relatively unaffected by the field. The resulting WebThe crystal field theory is based on the assumption that the chromophore {ML n} of a coordination compound can be described by the model according to which the central …
