Abstract :

The formation of complexes of La (III), Ce (III), Pr (III),Nd (III),Sm (III) and Eu (III)complexes with 5–ethoxy carbonyl–4–(4–chloro phenyl)–6–methyl–3,4–dihydropyrimidine–2(1H)–0ne was studied spectrophotometerically at (302 � 0.1) K and ionic strength � = 0.1 mol.dm . The stability constants have been–investigated in a 70% THF–aqueous mixture by the Job�s continuous variation method. The results obtained of stability constants are in good concordance the values obtained by the real stability constant by pH metric technique.
