摘要：

The reaction of Pr(III) and Nd (III) metal ions with L-1 : 3 (2'-chlorophenyl) - 4-benzoyl - 5 (2-hydroxy phenyl) pyrazole, L-2 : 3 (2'-chlorophencyl) - 4-pyridoyl -5 (2-hydroxy phenyl) pyrazole, L-3 : 3 (2'-aminophenyl)- 4-pyridoyl -5 (2-hydroxyl phenyl) pyrazole and L-4 : 3 (4'-chlorophenyl) - 4-Benzoyl -5 (2-hydroxy-phyenyl) pyrazole, have been studied pH-metrically at 0.1M ionic strength at 28 +/- 0.1 degrees C in 70% ethanol -water mixture. The data obtained were used to estimate the values of proton-ligand (pK) and metal-ligand (logK) stability constants. It is observed that Pr(III) and Nd(III) metal ions formed 1:1 and 1:2 complexes with all the ligands.
