The 17H17N3O2S, consists of two independent molecules, A and B, with different conformations: in molecule A, the dihedral angles between the central benzene ring and the pendant tolyl and carbamothioylhydrazono groups are 71.12 (9) and 5.95 (8)°, respectively. The corresponding angles in molecule B are 50.56 (12) and 26.43 (11)°, respectively. Both molecules feature an intramolecular N—H⋯N hydrogen bond, which closes an S(5) ring. In the crystal, molecules are linked by N—H⋯O, N—H⋯S and C—H⋯O hydrogen bonds, generating a three-dimensional network.

A 250-ml two neck RB flask was taken and fitted with condenser and an addition funnel. 0.5mol of 4- hydroxy acetophenone was taken and 200ml of chloroform was added to it with stirring. The reaction mixture was cooled at 5-10°c. 0.5mol of para-tolouyl chloride was added drop wise to the reaction mixture. Stirring was continued for another 15mins and 0.5mol of potassium carbonate was slowly added. Reaction was continued for 2 hours and monitored using TLC. The reaction mass was transferred into 1l beakers and washed twice with water (2x250ml). The chloroform layer was separated and washed with 10% NaOH solution (2x250ml). The chloroform layer was separated and dried with anhydrous sodium sulphate. The chloroform layer was filtered and concentrated under reduced pressure using rotary vacuum, cooled and hexane was added to it. Solid was precipitated, filtered and the product was air dried. Thiosemicarbazide (0.1mole) dissolved in 20 ml of 1N hydrochloric acid was added slowly in constant stirring to 4-Methyl-benzoic acid 4-acetyl-phenyl ester (0.1mole) dissolved in 50 ml of ethanol. After addition of thiosemicarbazide, novel 4-(1-(2-carbamothioylhydrazono)ethyl) phenyl 4-methylbenzoate (in solid form) was formed within 4 mins. The precipitate was filtered and washed with water, followed by Hexane wash and the product was air dried. After purification the compound was recrystallised from CHCl3 solution to yield colourless blocks.
The hydrogen atoms were placed in calculated positions with C—H = 0.93Å to 0.96 Å & N—H = 0.85 Å to 0.86 Å and refined in the riding model with fixed isotropic displacement parameters:Uiso(H) = 1.5Ueq(C) for methyl group and Uiso(H) = 1.2Ueq(C) for other groups. The hydrogen atom H2Awas obtained from the difference fourier map.
Thiosemicarbazone and its derivatives are a class of O, N, S-tridentate donor ligands capable of stabilizing both higher and lower oxidation states of transition metal ions. The biological activities of these ligands are linked to their chelating ability with transition metal ions through phenol O, azomethine N and thiolate S atoms (Seena et al., 2006). Thiosemicarbazones are significant intermediates in drugs synthesis, formation of metal complexes and heterocycles such as thiadiazolines preparation (Sau et al., 2003). Thiosemicarbazones are reported as compounds which present significant antifungal activity. Their metal complexes also exhibit antifungal properties (Reis et al., 2013).
Thiosemicarbnazones are inhibitors of DNA replication and also of many
This inhibitory activity defends the level of interest given to them in the fight against microbial and parasitic diseases. Thiosemicarbazones have many biological activities such as antiviral, antibacterial, antitumor, African trypanosome (Fatondji et al., 2013).The title compound, C17H17O2N3S1, crystallizes in triclinic P -1
The of title compound contains two molecules which are shown in Fig.1. The acetophenone thiosemicarbazone fragment in molecule A is almost planar with maximum deviation -0.087 Å and in molecule B maximun deviation is -0.592 Å. The methylbenzoate (C1/C2-C8/O1/O2) and acetophenone thiosemicarbazone (C9-C16/N1/N2/C17/N3/S1) make a dihedral angle of 71.12 (1) ° in molecule A and 50.60 (1) ° in molecule B. The thiosemicarbazone group adopts an extended conformation,which can be seen from the torsion angle value of S1/C17/N2/N1 = -177.4 ° in molecule A and 174.1 ° in molecule B. The methylbenzoate and acetophenone thiosemicarbozone lie in a plane which is evidenced by the torsion angle value of C5/C8/O2/C9 = 179.4 ° in molecule A and 174.8 ° in molecule B.The
features both intramolecular & intermolecular interactions of type N—H···N, C—H···O, C—H···N, N—H···S and N—H···O (Table. 1 & Fig. 2). In the crystal packing N—H···S type of intermolecular interaction shows R22 (8) dimer formation.For background to the biological activity of thiosemicarbazone derivatives, see: Reis et al.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Thiosemicarbazone and its derivatives are a class of O, N, S-tridentate donor ligands capable of stabilizing both higher and lower oxidation states of transition metal ions. The biological activities of these ligands are linked to their chelating ability with transition metal ions through phenol O, azomethine N and thiolate S atoms (Seena et al., 2006). Thiosemicarbazones are significant intermediates in drugs synthesis, formation of metal complexes and heterocycles such as thiadiazolines preparation (Sau et al., 2003). Thiosemicarbazones are reported as compounds which present significant antifungal activity. Their metal complexes also exhibit antifungal properties (Reis et al., 2013).
Thiosemicarbnazones are inhibitors of DNA replication and also of many proteases. This inhibitory activity defends the level of interest given to them in the fight against microbial and parasitic diseases. Thiosemicarbazones have many biological activities such as antiviral, antibacterial, antitumor, African trypanosome (Fatondji et al., 2013).
The title compound, C17H17O2N3S1, crystallizes in triclinic P -1 space group. The asymmetric unit of title compound contains two molecules which are shown in Fig.1. The acetophenone thiosemicarbazone fragment in molecule A is almost planar with maximum deviation -0.087 Å and in molecule B maximun deviation is -0.592 Å. The methylbenzoate (C1/C2-C8/O1/O2) and acetophenone thiosemicarbazone (C9-C16/N1/N2/C17/N3/S1) make a dihedral angle of 71.12 (1) ° in molecule A and 50.60 (1) ° in molecule B. The thiosemicarbazone group adopts an extended conformation,which can be seen from the torsion angle value of S1/C17/N2/N1 = -177.4 ° in molecule A and 174.1 ° in molecule B. The methylbenzoate and acetophenone thiosemicarbozone lie in a plane which is evidenced by the torsion angle value of C5/C8/O2/C9 = 179.4 ° in molecule A and 174.8 ° in molecule B.
The crystal structure features both intramolecular & intermolecular interactions of type N—H···N, C—H···O, C—H···N, N—H···S and N—H···O (Table. 1 & Fig. 2). In the crystal packing N—H···S type of intermolecular interaction shows R22 (8) dimer formation.
