A new azomethine based on N-aminofluorescein and ortho-tosylaminobenzaldehyde has been synthesized. Structure and properties of the obtained compound have been studied by means of IR, 1H NMR, and electron absorption spectroscopy as well as potentiometry. Using the DFT method, quantum-chemical simulation of electronic absorption spectra has been performed. The complexation of the obtained azomethine in solutions with Cu2+, Ni2+, and Co2+ cations has been studied. Metal chelates (1:2) with Cu(II), Ni(II), Zn(II), and Cd(II) have been isolated. Octahedral structure of the coordination site has been suggested for the obtained metal chelates.
