Bonding in Coordination Compounds: Crystal Field Theory

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 (CFT): salient features of CFT- Crystal field splitting patterns of transition metal ion d-orbital in tetrahedral, octahedral and square planar geometries.
