The title compound, C11H15N3OS, is a thiosemicarbazone derivative of the raspberry ketone rheosmin [systematic name: 4-(4-hydroxyphenyl)butane-2-one]. The molecule deviates from planarity, with the bridging C—C—C=N torsion angle equal to −101.3 (2)°. The maximum deviation from the mean plane of the non-H atoms of the thiosemicarbazone fragment [C=N—N—C(= S)—N] is 0.085 (5) Å for the Schiff base N atom, and the dihedral angle between this mean plane and the aromatic ring is 50.31 (8)°. In the crystal, molecules are linked by N—H⋯O, N—H⋯S and O—H⋯S hydrogen bonds, forming a three-dimensional structure, with the molecules stacked along [011].
Keywords: crystal structure; thiosemicarbazone; raspberry ketone; hydrogen bonding; three-dimensional.

Our work is actually dedicated to the synthesis and structural determination of thiosemicarbazone derivatives of natural products. The thiosemicarbazone unit is well known for its biological properties as well as for its importance in coordination chemistry (Lobana et al., 2009). Herein, we contribute to the thiosemicarbazone chemistry by the synthesis and
of raspberry ketone thiosemicarbazone. The raspberry ketone is a natural product with great demand on the market and its synthesis has already been reported and optimized (Hoffmann & Degner, 1981).In the title molecule, Fig. 1, the thiosemicarbazone unit is nearly planar showing a torsion angle for the N1—N2—C10—N3 entity of -3.1 (3)°. The maximum deviation from the mean plane of the non-H atoms of the C9/C10/N1/N2/N3/S1 fragment amounts to 0.085 (5)°. The angle between this mean plane and the aromatic ring is 50.31 (8)°. This strong tilting is possiblly due to
around the sp3-hybridized C7 and C8 atoms (Fig. 1).In the crystal, molecules are connected by N—H···O, N—H···S and O—H···S hydrogen bonds, with bridging sulfur atoms, into a three-dimensional H-bonded network (Figs. 2 and 3, and Table 1). The molecules are arranged along the [011] direction, but the hydrogen bonding interactions are present along all three directions (Fig. 3).
The synthesis of the title compound was adapted from a procedure reported previously (Freund & Schander, 1902). In a hydrochloric acid catalyzed reaction, a mixture of 4-(4-hydroxyphenyl)-2-butanone (raspberry ketone) (10 mmol) and thiosemicarbazide (10 mmol) in ethanol (80 mL) was refluxed for 5 h. After cooling and filtering, the title compound was obtained. Yellow crystals suitable for X-ray diffraction were obtained by slow evaporation of asolution in methanol.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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. |
