“…Salicylic acid has often been chosen for Al(III) and Fe(III) spectrophotometric determination in water samples [34,35], its complexation constants towards these two metallic ions are very well known [36,37]. This new resin has been packaged into a methyl polymetacrylate micro-column of 6 mm inner diameter and 10 mm length, affording thus flow-through percolation of samples.…”

“…43 An 27 Al NMR study 44 was studied by various spectroscopic and potentiometric means and kinetic and stability data obtained for each ligand across pH. 75 The geometry of the substituted acetylacetonate complex [Al{OCMeC(4-NC 5 H 4 )CMeO} 3 ] (AlL 3 ) is rather irregular, the ligands being separated by angles of roughly 89u, 126u and 145u (sum 360u), which allows the 89u moiety to be used as a near right-angular building block. Thus, [CoCl 2 AlL 3 ] units can form a square array with the Co centres acting as square planar linkages, and [CdBr 2 (MeOH)AlL 3 ] units can do so with the Cd centres acting as T-shaped linkages.…”

Highlights of Group 13 chemistry in 2004 include the account of a chirallyrobust cage made from achiral ligands bridging Ga(III), normally classed as being a labile metal centre: moreover, this cage encapsulates a chiral catalyst so affording both size and shape selectivity in the products. 1 Generally, as last year, Roesky and co-workers continue to impress both in the volume and in the imaginative nature of their work, especially that concerning the chemistry of the {(dkio)Al} moiety.

“…During complexation, these antioxidants may coordinate with Be 2+ in several possible binding modes, in particular DA may form complex in salicylate or catecholate manner as depicted in Fig. 1 [17,18]. It was an interesting subject to study the ligand possible binding modes towards metal ion.…”

Equilibrium studies of beryllium with 2,3-dihydroxybenzoic acid, 3,4-dihydroxybenzoic acid and gallic acid in an aqueous solution at 310.15 K, an ionic strength of 0.15 mol•dm −3 NaCl and pH 2.5 to 11.0 were investigated by the pH-potentiometric method. Stability constants of the complexes were determined by HyperQuad2008 and presented as logβ. Contributing binding sites of these ligands were evaluated by comparing its logβ with some structurally related ligands such as catechol and salicylic acid. Spectrophotometric measurements were done to confirm the formation of the complex species. Geometry optimization and frequency analysis of the complexes were performed by using Gaussian09W program to verify the contributing binding sites. The results indicate that the ability of ligands in preventing the hydrolysis of Be 2+ follows the order: 3,4-dihydroxybenzoic acid N 2,3dihydroxybenzoic acid N gallic acid.
