Ch. 11: EDTA Titrations
chem320.cs.uwindsor.caThe equilibrium constant for the reaction of a metal with a ligand is called the formation constant, Kf, or the stability constant: In many transition metal complexes, EDTA engulfs the metal ion, forming the six-coordinate species. If you build a space-filling model of a six-coordinate metal-EDTA complex, you find strain in the chelate rings.

CHAPTER 10: COORDINATION CHEMISTRY II: BONDING
www.chem.uci.eduIn general, stability constants decrease as more ligands are added; the sequence for nickel is the common one. The huge drop in stability constant between the second and third ethylenediamine on Cu2+ is a result of the d 9 Jahn-Teller effect. The first two en ligands add in a square-planar geometry, with water molecules in the axial positions,

Chemistry of Iron in Natural Water - USGS
pubs.usgs.govThe inorganic complexes most likely to be found in natural waters are those formed with chloride, fluoride, phosphate, sulfate, and carbonate ions. Organic complexes also may be present. The ferrous oxidation state, less strong in its complexing properties than the ferric, forms few inorganic complexes. Ferrous hydroxide,
