| Inhoud: |
The complexation of a recently synthesized vic-dioxime derivative, 1-({2-[(2-aminoethyl) amino]ethyl}amino)-6-methyl-9H-xanthen-9-one with Ni(II) in N,N-dimethylformamide, was investigated by spectrophotometric and conductometric methods. The possible molecular geometries, binding, and spectroscopic properties for the formed complexes were theoretically studied in detail by the Hyperchem program. The stoichiometry of the complex species was determined from spectrophotometric molar ratio methods at 25°C. The spectral data were further treated by KINFIT to calculate the formation constants of the 1 : 1 and 1 : 2 complexes and their molar absorptivities. Program DATAN was used to calculate the spectral behavior of the complexes in the wavelength range ∼380-∼550 nm for different mole ratio solutions. |
