Electrophoretic Studies on Medicinally Important Binary Metal Complexes (system: Copper(ii) / Manganese(ii) / Uranyl(ii) – Sarcosine)
Quantitative indication of the process of forming a complex comes from the evaluation of the stability constants which characterize the equilibria corresponding to the successive addition of ligands. A technique involving the use of paper electrophoresis is described for the study of binary complex system in solution. The first and second stability constants of metal(II) – sarcosine complexes w...
متن کاملAssembly of a trinuclear metallo-capsule from a tripodal tris(beta-diketone) derivative and copper(II).
A new metallo-capsule has been synthesised that consists of three copper(II) ions and two molecules of a tris-deprotonated tripodal ligand in which three 2,4-pentanedione groups are linked via their gamma-carbons through thioether spacers to the 1,3,5-positions of a triazine core.
متن کاملCatalytic effects of metal chelate compounds.
This paper is essentially a progress report on the developments in the field of metal chelate catalysis since the first review of this subject fifteen years ago'. For the purpose of defining the scope of this field, metal chelate catalysis is considered to include any reaction that is altered or modified by metal ions through chelate ring formation, as well as reactions of metal chelates themse...
متن کاملSulphonic acid)-5-Pyrazolone [CSMACSP] as a Spectrophotometric Reagent: Studies on Cu(II) Chelate
Numerous heterocyclic azo dyes have been reported for the spectrophotometric determination of Cu(II). Here, we report a new heterocyclic azo dye 1-(2'Chloro-4'-sulphophenyl-3-methyl-4-azo-(2"carboxy-5"-sulphonic acid)-5-pyrazolone [CSMACSP] for the spectrophotometric determination of Cu(II). The method is simple, rapid and sensitive. Light green colour 1:1 (M:L) complex formed between Cu(II) an...
متن کاملRelationships between structure, retention and biological activity of some Schiff base ligands and their complexes.
The lipophilicity of a series of Schiff base ligands and their complexes with nickel(II) and copper(II) has been determined by reversed-phase thin-layer chromatography using binary dioxane-water mobile phase. Chelate ligands were prepared by condensation of diamine and the corresponding beta-diketone. Copper(II) and nickel(II) complexes with chelate ligands containing ethane-1,2-diamine or prop...
