WebThe stability of a complex particle (ion or molecule) in solution is determined by the nature of the central atom and the ligands. The most important characteristics of the central atom, determining the stability of the complex compound, are the degree of oxidation (charge on the central ion in the case of ionic complexes), the dimensions, and the electronic structure.
