Abstract
In this study, a compound, N-(3-methyl-4-oxo-4H-(1,3,4)thiadiazo- lo(2,3-c)(1,2,4)triazin-7-yl)benzamide, was obtained via two different reac- tions: 1) reaction of 4-amino-6-methyl-3-(methylthio)-1,2,4-triazin-5(4H)-one with benzoyl isothiocyanate under removal of methanethiol and 2) reaction of 4-amino-3,4-dihydro-6-methyl-3-thioxo-1,2,4-triazin-5(2H)-one with benzoyl isothiocyanate under elimination of hydrogen sulfide. In both reactions, a new bond between sulfur and nitrogen atoms was formed and a five-membered ring was created. The oxo thiadiazolo benzamide was characterized by IR, 1 H-NMR and 13 C-NMR spectroscopy, and mass spectrometry. X-Ray crystallography was used to shed light on the structure of this new compound. Two new com- plexes could be generated by coordination of the oxo thiadiazolo benzamide to Pd(II) and Ni(II) ions. These complexes were analyzed by IR, 1 H-NMR and 13 C- -NMR spectroscopy, conductometry and thermal gravimetry (TGA). The theo- retical QM calculation GIAO was also applied to predict the structure of the Pd complex.
