According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point charges consisting of the ligands. … WebCrystal Field Theory is one of the most important theory for explaining nature of bonding in coordination compounds. It deals with electrostatic interactions between metal ion and the ligands forming complexes with varying geometries like octahedral, tetrahedral, square planar etc. According to this theory, the donor electrons of the incoming ...
