For high-spin complexes of the divalent ions of first-row transition metals, the stability constant for the formation of a complex follows the order: Mn (II) < Fe (II) < Co (II) < Ni (II) < Cu (II) > Zn (II) This order was found to hold for a wide variety of ligands The ionic radius is expected to decrease regularly for Mn2+ to Zn2+. The stability of a coordination compound (aq) means the degree of association between the two species involved in the state of equilibrium. A number of factors influence joint stability. gqK/kBh2Xdat~eBe H2O forms more stable complexes with a central metal atom with a _______ oxidation state.
