Acta Crystallographica Section E , 2013, DOI: 10.1107/s1600536812051458
Abstract: In the title compound, C18H15N5O2S, a weak intramolecular C—H...S hydrogen bond results in a small dihedral angle of 3.71 (9)° between the methylphenyl and triazole rings, which, in turn, form dihedral angles of 80.09 (8) and 77.32 (8)°, respectively, with the benzoxazolone mean plane. In the crystal, N—H...O hydrogen bonds link molecules into chains along [001], and weak C—H...N hydrogen bonds and π–π interactions between the five- and six-membered rings [centroid–centroid distances = 3.5074 (11) and 3.616 (1) ] consolidate the crystal packing.

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812039529
Abstract: In the title compound, C17H17N3O2S, the dihedral angle between the aromatic rings is 6.3 (5)° and the C=N—N=C group is statistically planar [torsion angle = 179.8 (8)°]. The conformation of the thiazine ring is an envelope, with the S atom displaced by 0.823 (9) from the mean plane of the other five atoms (r.m.s. deviation = 0.012 ). In the crystal, C—H...O interactions link the molecules into C(5) chains propagating along [101]. The chains are consolidated by weak aromatic π–π stacking between the benzene and toluene rings [centroid-to-centroid separation = 3.826 (5) and interplanar angle = 6.3 (4)°].

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810048853
Abstract: All the non-H atoms of the title compound, C8H10N4S, lie on a crystallographic mirror plane and an intramolecular N—H...N hydrogen bond helps to stabilize the molecular conformation. In the crystal, molecules are linked through intermolecular N—H...N hydrogen bonds, forming zigzag C(7) chains along the a axis.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810015850
Abstract: In the title molecule, C8H9N3O3S, the thiosemicarbazide =N—NH—C(=S)—NH— fragment is twist a different degree of twist in the three independent molecules [dihedral angles = 7.6 (1), 11.6 (1) and 20.7 (1)°]. Intramolecular O—H...N and O—H...O hydrogen bonds occur. In the crystal, the hydroxy and amino groups are hydrogen-bond donors and the O—H...O, O—H...S and N—H...O hydrogen bonds generate a layer motif.
A Novel Hydrazinecarbothioamide as a Potential Corrosion Inhibitor for Mild Steel in HCl  [PDF]

Materials , 2013, DOI: 10.3390/ma6041420
Abstract: 2-(1-methyl-4-((E)-(2-methylbenzylidene)amino)-2-phenyl-1H-pyrazol-3(2H)-ylidene)-hydrazineecarbothioamide (HCB) was synthesized as a corrosion inhibitor from the reaction of 4-aminoantipyrine, thiosemicarbazide and 2-methylbenzaldehyde. The corrosion inhibitory effects of HCB on mild steel in 1.0 M HCl were investigated using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). The results showed that HCB inhibited mild steel corrosion in acidic solution and inhibition efficiency increased with an increase in the concentration of the inhibitor. The inhibition efficiency was up to 96.5% at 5.0 mM. Changes in the impedance parameters suggested that HCB adsorbed on the surface of mild steel, leading to the formation of a protective film. The novel corrosion inhibitor synthesized in the present study was characterized using Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectral data.
