In the title compound, C22H17ClN4O2S2, both benzoyl groups are trans to the thiono group across their C—N bonds. The two methyl­ene carbamothioyl formamide fragments of the benzoyl­thio­urea side arms make a dihedral angle of 87.00 (10)°. The mol­ecule is stabilized by intra­molecular N—H⋯O, N—H⋯S and C—H⋯·S hydrogen bonds. In the crystal, mol­ecules are linked by N—H⋯O and N—H⋯S inter­molecular hydrogen bonds into zigzag chains along the a axis.

Fringescalesardinella or TambanSisik bones have been discovered can be utilized as sunscreen agent in cosmeceuticals. Its flesh is the main ingredient in keropoklekor or fish crackers in Malaysia and the bones contained very high hydroxyapatite (HAp), (Ca10(PO4)6(OH)2) compound which exhibit as UV light absorber. The percentage yields obtained from the hydrothermal extraction consist of 41.2 ± 0.66 % (w/w) of HApwhich was almost half of the dry weight of 100 g samples.The additional of manganeseand ferum,initiated the novel sunscreen materials from hydroxyapatite-Fe and hydroxyapatite-Mn doped (modified bones). The unmodified HAp recorded with SPF 20 and modified HAp-Mn measured with SPF 40. Modified HAp-Fe emulsions were recorded with SPF 50 as the highest SPF value. Therefore, the bones have been characterized using Fourier Transform Infrared Radiation (FTIR)spectroscopy and x-Ray diffraction (XRD).The results obtained clearly indicated that the HAp existence in waste of Fringescalesardinella bones with addition of FeCl2which exhibits high potential as sunscreen compared to manganese and unmodified bones. Thus, the utilization of waste from the fish bones not only produce value-added products from low-cost resources, but also help in reducing pollution to the environment and preserved the global sustainability.

One-pot synthetic method was adopted to prepare three isomers 4-( ortho- fluorophenyl)thiosemi- carbazide), 4-( meta- fluorophenyl)thiosemicarbazide and 4-( para- fluorophenyl)thiosemicarbazide. The products were obtained in ethanolic solution from a reaction between ortho, meta and para derivatives of fluorophenyl isothiocyanate and hydrazine hydrate. This work presents the theoretical Molecular Electrostatic Potential (MEP) and Highest Occupied Molecular Orbital-Lowest Unoccupied Molecular Orbital (HOMO-LUMO) computational data through Gaussview 5.0.9 and Gaussian09 software. Experimental Cole-cole plot for conductivity determination was also illustrated. The present data is important to manipulate the properties of compounds according to the position of a fluorine atom.

New compound, namely (Z)-1-[4-(trifluoromethyl)benzylidene]thiosemicarbazide was successfully synthesized using thiosemicarbazide with 4-(trifluoromethyl)-benzaldehyde in ethanol solution. The data presented in this articles is related to our research articles entitled “Crystal Structure of (Z)-1-[4-(Trifluoromethyl)benzylidene]thiosemicarbazide” (Osman et al., 2017) [1]. This work shows the continue data from experimental spectroscopic measurement which are Fourier Transform Infrared (FTIR) and 13C Nuclear Magnetic Resonance (13C NMR). Assessment on the correlation with theoretical computational data was also carried out through GaussView 5.0.9 and Gaussian09 software. Molecular Electrostatic Potential (MEP) and Highest Occupied Molecular Orbital–Lowest Unoccupied Molecular Orbital (HOMO-LUMO) were also illustrated.
