Complexes of d10 ions with amides and amidines. Part I. Dissociation constants of ligands and stability constants of mercury(II) complexes

Abstract

Complex formation between mercury(II) and acetamide, hydroxyisobutyramide, phenylglycolamide, phenyl-lactamide and their corresponding amidines, and α-methyl-α-hydroxybutyramidine has been studied by pH titration methods. In all cases, complexes of the form HgLCl, HgL₂, and HgLOH were detected, where L represents an amidine base or an amidate ion. Equilibrium constants for these processes are reported, and the significance of the hydrolysis step is discussed.
