3-Hydroxy-4-pyridinonate complexes

Stereochemistry and Degree of Hydration of 3-Hydroxy-4-pyridinonate Complexes of... 

To put hydroxypyranonate and hydroxypyridinonate complexes in context, stability constants for kojate and l,2-dimethyl-3-hydroxy-4-pyridinonate complexes of Mg, Al, Fe, and Gd are compared with stability constants for complexes of these cations with a few other ligands in Table III. That these hydroxypyranonate and hydroxyp5rr-idinonate ligands form stable complexes is immediately apparent. In this section we shall present and discuss a generous, but far from... 

Stepwise stability constants decrease regularly in the normal manner 178), log > log K2 > log K, as may be exemplified by the values for the Ni -maltolate system, viz. 5.5, 4.3, and 2.7, respectively 179). Stability constants (log Kf) for a selection of 3-hydroxy-4-pyranonate and 3-hydroxy-4-pyridinonate complexes of some first-row transition metal 2+ cations are listed in Table IV 10,128,180—184). The values for the 3d transition metal cations conform to the long-established Irving-Williams order... 

We present a selection of solubilities of 3-hydroxy-4-pyridinonate complexes of cations in Table XVII 114,143,144,233-241) and Table XVIII (237), to give some impression of the effects of their variation with the nature of the complex and of the solvent. It is very difficult...
