The synthesized Pd(II) complexes involved -NH group attached to C=S moiety. The 1H proton NMR taken in DMSO-d6 solvent consisted of a very broad peak at 4.8 ppm with an integration of 6. They are no functional groups in the structure of the complex causing a broad peak other than -NH. But the peak for -NH is found correctly as a sharp singlet at 8.5 ppm. The complexes are characterized by single crystal NMR and ESI-MS spectrum. So, what may be the reasons for such a broad peak in the spectrum and can we rely on such a spectrum? Is it due to the presence of D2O in DMSO-d6 interacting with the complex?
