Complexes of yttrium(III) formed with 5-sulphosalicylic acid, 5-SSA (H3L), and 5-nitrosalicylic acid, 5-NSA (H2L), were investigated in 0.1 mol.dm −3 sodium perchlorate ionic medium at 25.0 ± 0.1 ◦C potentiometrically for various molar ratios of Y(III) to these salicylic acid, SA (H2L), derivatives. Y(III) forms YL and YL3− 2 type complexes with 5-SSA that have rather high stabilities (log β1= ...

The complexes of the type MLXn where M=Co(III),Fe(III), Mn(III), Ti(III),V(III), Ru(III),Ru(II) MoO(V),MoO2(VI) and UO2(VI),X=Cl/NO3, n=2/4, and L is the thiosemicarbazide ligand derived from reaction between benzofuran-2-carboxy hydrazide and phenylisothiocyanate(BCPT)were prepared. All the complexes isolated in solid state, are stable in air and characterized by the elemental analyses, IR, el...

Quantitative studies of complex formation from the determination of stability constants of the binary complexes of metal (II)/(III)alizarin and also the mixed complexes of metal (II)/(III)alizarin-NTA have been described using paper electrophoretic technique. The stability constant of metal-(II)/(III)-alizarin are found to be 105.14, 104.84, 104.44 and 104.14 and mixed complexes of metal (II)/(...
