Complexation of heterocyclic azo compounds with transition metal ions as found by the laser-induced desorption/ionization method

Аннотация

The Pd, Mn, La, and Rh complexes with the heterocyclic azo compounds were studied by the laser-induced electron transfer desorption/ionization (LETDI) method. The optimum parameters of laser irradiation were found, and the compositions of the complexes were determined. The quantum chemical simulation of the compositions of the complexes was performed on the basis of the data of mass spectrometry. It is shown that laser-induced electron transfer desorption/ionization is an effective tool for the high-sensitive determination and identification of metal complexes.
