Abstract
the formation of binary and ternary complexes of EU(III) with 7-carboxy methoxy-4-methyl coumarin (L1) and nucleotides guanosine 5,-monophosphte (5,-GMP), adenosine 5,-triphosophate (5,ATP), has been studied potentiometrically at (25.0# 0.1) C and ionic strength I = 0.1mol dm 3(KNO) in 155 V/V ethanol-water mixture solvent. the acid properties of the ligands were investigated and discussed.
