Chap 24. Transition Metals and Coordination Compounds
... Bonding in a complex ion is considered to be an electrostatic attraction between the positively charged nucleus of the central metal ion and electrons in the ligands. Repulsions also occur between the ligand electrons and electrons in the central ion. Crystal field theory focuses on the repulsions b ...
