Ligands The ‘H and "C NMR spectra of H;L' in CDCI3 recorded at 400 MHz, along with their spectral assignments are given in Figs. 2.8 and 2.9. The sharp peaks at 5 = 14.56 and 15.45 ppm are assigned to NH protons as they are singlets and their considerable decrease in intensity on D20 exchange. The downfield shifts of these protons are due to possible hydrogen bonding interactions with adjacent nitrogen atoms. Hydrogen bonding interaction decreases the electron density around the proton, and thus causes shifting of resonance absorption to a lower field [23]. The singlet nature of these peaks is attributed to the absence of any nearby protons for coupling interactions. The '3 C NMR spectrum of H2L' (Fig. 2.9) shows a well distinct peak at 177.69 ppm assigned to thione carbon, which is absent in the DEPTl35 spectrum (Fig. 2.9). The absence of any peaks at ~4 ppm for —SH proton [21] in 'H NMR along with these observations suggest the exclusive presence of the thione tautomeric form of H2L' in solution phase. The absorptions for pyridyl hydrogen atoms are seen between 7.19 and 8.73 ppm. As the electronegative pyridyl nitrogen atoms cause a downfield shift for adjacent protons, the peaks at 8.73 (lH, d), 8.62 (1H, d), 8.50 (1H, d) and 8.21 ppm (1H, d) are assigned due to the protons of carbons near to pyridyl nitrogens. The remaining signals centered at 5 = 7.92(lH, d), 7.84 (1H, t), 7.75 (3H, m), 7.55 (1H, d), 7.51 (lH, d), 7.38 (1H, t), 7.31 (1H, t), 7.25 (1H, t), 7.20 ppm (2H, d) are assigned as the remaining twelve protons of the four pyridyl rings. The BC NMR spectrum shows well distinct 21 peaks, of which two are of double intensity, showing the presence of 23 carbon atoms and l6 of which are retained in DEPTl35 spectrum as expected. 5l
