Complex formation between copper(II) and thiobarbiturates.

Complex formation between copper(II) and selected thiobarbiturates was investigated via spectrophotometric procedures with absolute methanol as the solvent. The composition of the complexes proved to be 1:2 metal-ligand. The formation constants were computed using different procedures, and the results were reproducible. The electronic absorption spectra of the selected thiobarbiturates were studied. Spectrophotometric determination of the drugs was investigated.

Chemical Phenomena

Spectrophotometric study of complex formation between oxovanadium (IV) and antiamebic drugs.

Complex formation between oxovanadium(IV) and the antiamebic drugs 5, 7-dibromo-8-quinolinol and 5, 7-dichloro-8-quinolinol was studied in the pH 1.5-2.0 range, using ethanol, dioxane-water, and dimethylformamide as solvents. The composition of the formed complexes was determined by more than one procedure. In ethanol and dioxane-water, the 1:1 and 1:2 complexes were formed; in dimethylformamide, the 1:1, 1:2 and 1:3 complexes were formed. The stability constants were computed using two procedures: the molar ratio method and the extrapolation method. The reproducibility or results in satisfactory.
