Spectral and theoretical studies of N-p-(ethylbenzene)thiobenzohydroxamic acid metal chelates
چکیده انگلیسی
The preparation of N-p-(ethylbenzene)thiobenzohydroxamic acid chelates with several metal ions and their spectral properties are described in this paper. This is followed by a theoretical study of metal complexes of some thiohydroxamic acids, as well as the prepared chelates. The electronic properties of the metal complexes are discussed. The experimental and theoretical electronic spectra are also compared. A possible reason for the smaller pKa values of thiohydroxamic acid complexes than those of the corresponding hydroxamic acids is given.
