A New Example 111/113Cd–1H Heteronuclear Coupling 1HNMR of Cd(II) as a Toxic Trace Metal

Abstract

As we know spectroscopy studying is one the most important subjects in Chemistry. One of the most important types of spectroscopy measurements to indicate the structural properties such as type and number of atoms is NMR study. For this mean, we need to synthesis of new compounds and we should try for studying their spectroscopy properties. Herein, we report the synthesis of a new macroacyclic Schiff base ligand (H₃L) obtained from the condensation reaction of 2-[3-(formylphenoxy)-2-hydroxy propoxy] benzaldehydewith 2-aminophenol and characterized with IR, ¹H NMR and ¹³C NMR spectrometry. The related metal complexes of Cd(II) and Zn(II) are prepared with above ligand and characterized by ¹³C,¹HNMR, IR and elemental analysis spectroscopy methods. The spectroscopy studying of the prepared compounds in this paper shows that all of them are pure. In addition, the microanalysis results show that the phenolic groups coordinated to the metal ions as OH and the proton hasn’t separated.In the¹H NMR spectrum of the cadmium complex signal of the imine proton has two satellite peaks with intensities in 1:6:1 due to the coupling with neighboring ¹¹³Cd NMR spectroscopy
