摘要：

The stepwise stability constants of the 1:1, 2:1 and 3:1 complexes of bidentate 1,2-dimethyl-3-hydroxy-4-pyridinone (DMHP) with divalent and trivalent metal ions have been determined in KCl supporting electrolyte (0.100 M) at 25.0-degrees-C. The overall log stability constant (log beta(ML3) = [ML3]/[M3+][L-]3) for the Fe(III) and Ga(III) complexes are high, 35.88 and 35.76, respectively. The log beta(ML3) values for the Al(III) and In(III) complexes with DMHP are 32.62 and 31.71, respectively, while that for the weak complex with Gd(III) is 17.33. The divalent metal ions of Cu(II), Ni(II), Co(II) and Zn(II) form stable 1:1 and 2:1 complexes with DMHP.
