Abstract

Bivalent copper and the Schiff's base pyridylalpydidylhydrazine form two compounds, composed respectively of one molecule and of two molecules of the organic compound to one atom of copper, and having ultra violet absorption spectra differing only in the value of the molar extinction coefficients at the absorption maxima, 15,100 and 22,450, respectively at 345 mμ. The respective formation constants are 2.4 x 10⁵ and 2.8 x 10⁵ as determined from spectrophotometric data, the method used being unusual in that the ultra violet absorption data provided a direct measure of the free ligand present.
