- W2114508741 abstract "AbstractA new tetraazamacrocycle containing two 5-chloro-8-hydroxyquinoline side arms, L 1 , was synthesized. The protonationconstants of L 1 and the stability constants of its complexes with Cu 2 ,Zn 2 ,Cd and Pb were determined by potentiometric orspectrophotometric methods, at 20 8C in methanol:water (5:1, v/v) and ionic strength 0.10 mol dm 3 in tetrabutylammonium nitrate(TBAN). Compound L 1 has three high protonation constants, the most basic centres being both phenolates of the arms. Mono- anddinuclear complexes were found in solution for all the metal ions, the complexes of copper are thermodynamically very stable, andthe dinuclear complexes of lead(II) are the predominant species even in 1:1 mixtures. UV / Vis spectra of some complexes and EPRof the copper ones confirmed the presence of dinuclear complexes.# 2003 Elsevier B.V. All rights reserved. Keywords: Tetraazamacrocycle; Stability constants; Dinuclear complexes; EPR copper complexes; 8-Hydroxyquinolinyl groups 1. IntroductionMacrocycles containing quinoline side arms havefound many applications as analytical reagents inabsorption spectrophotometry, fluorometry, solvent ex-traction, and partition chromatography [1,2]. Thesecompounds are also used as pesticides [2].The 8-hydroxyquinoline (HQ) forms a stable five-membered chelate ring with metal centres and verystable complexes with divalent transition and post-transition metal ions of the type M(HQ) , M(HQ)" @default.
