The Stability

Some physicochemical properties of sodium pentamethylenedithiocarbamate and complexes with Cu(II), Ni(II), and Fe(III) were studied. The bands in the electronic and IR absorption spectra were measured and characterized, and the possibility of coulometric determination of NaS2CN(CH2)5.2 H2O was examined. The conditions for spectrophotometric determination of trace quantities of Cu(II), Ni(II), and Fe(III) as dithiocarbamate complexes were established and the stability constants of the complexes were determined.

Iodine Complexes

The ir absorption spectra of some pyridine derivatives-iodine complexes were measured in the region 400 to 1400 cm−1 and the results are discussed. The effect of complex formation on the intensities of some of the bands was investigated. The thermodynamic constants of these complexes were calculated. It was found that the stability of the complex depends to a large extent on the electronegativity as well as the position of the substituent on the pyridine nucleus. The structures of formed complexes are discussed.
