3-Phenylamino-4-phenyl-1,2,4-triazole-5-thione was synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. Density functional theory calculations of the structure, natural bond orbitais, atomic charge distributions and thermodynamic functions of the title compound were performed at B3LYP/ 6-311G** and PBE1PBE/6-311G **levels of theory, respectively. NPA atomic charge distributions indicate that the title compound can be used as a potential multidentate ligand to coordinate with various metallic ions. Calculation of the second order optical nonlinearity was also carried out. The thermodynamic properties of Cp,m0, Sm0 and 77°m were calculated and correlative equations between the thermodynamic properties and temperatures were also obtained.

Abstract: The reaction of N-substituted hydrazinecarbothioamides with both 2-(bis(methylthio)methylene)malononitrile and ethyl 2-cyano-3,3-bis(methylthio)acrylate afforded various heterocyclic rings such as 5-amino-4-cyano-3-(methylthio)-N-phenyl-1H-pyrazole-1-carbothioamide, 5-amino-3-(methylthio)-1H-pyrazole-4-carbonitrile, 4-substituted-3-(substituted amino)-1H-1,2,4-triazole-5(4H)-thione, ethyl 5-amino-3-(methylthio)-1-(substituted carbamothioyl)-1H-pyrazole-4-carboxylate, and (Z)-ethyl 2-cyano-2-(5-(substituted amino)-1,3,4-thiadiazol-2(3H)-ylidene)acetate. However, under gentle heating, the reaction of the same starting substances behaved differently. The structure of the obtained products was fully characterized using different spectral techniques including infrared (IR), nuclear magnetic resonance (NMR), and mass spectrometry (MS) together with elemental analyses as well as single-crystal X-ray diffraction analysis.

In the reaction of hydroiodide of methyl ester of S-methylthio-semicarbazide with primary amines hydroiodides of 2-amino-1-substitutedguanidine were obtained (1). These compounds were then converted to respective 3-arylamino-4-substituted Δ2-1,2,4-triazoline-5-thione and 3- benzylamino-4-substituted Δ2-1,2,4 -triazoline-5-thione (2) in the reactions with isothiocyanates.
