(Received 30 August 2012; accepted 5 December 2012; online 8 December 2012)

In the crystal structure of the title compound, C11H15N3O2S, mol­ecules are linked by pairs of N—H⋯O and O—H⋯S hydrogen, forming inversion dimers. These dimers are linked by N—H⋯S hydrogen bonds, forming double-stranded chains propagating along the b-axis direction. The two C atoms of the end chain of the mol­ecule are disordered over two sets os sites [occupancy ratio 0.574 (9):0.426 (9)].

Comment top

Thiosemicarbazones emerged an important class of sulfur and nitrogen containing Schiff-bases due to their chemistry and potentially beneficial biological activities, such as antitumor,antibacterial, antiviral and antimalarial activities (Kasuga et al., 2003; Paterson & Donnelly, 2011). In a continuation of our studies on thiosemicarbazone Schiff-bases, we report the synthesis and crystal structure of the title compound, (I).

In (I) (Fig. 1), all bond lengths and angles are normal and in a good agreement with those found in the literature (Joseph et al., 2006).There is one molecule in the assymetric unit with the end atoms thermally disordered. This molecule exhibits intermolecular N—H···O and O—H···S hydrogen bonds (Table 2) forming a dimer along b axis. These dimers give rise to a zigzag pattern seen along c axis. Further the molecules are packed by weak π···π interactions [centroid–centroid distance 4.495 (5) Å]

Experimental top

The title compound (I)was synthesized by the reaction of 2-hydroxy-3-methoxy benzaldehyde (10 g, 0.1 mol) in 250 ml round bottom flask, 5% acetic acid-water solution of 4 N-methyl hydrazinecarbothioamide (0.1 mol) in ethanol solution and refluxed on a steam bath for 30–45 minutes. The crystalline product which formed was collected by filtration, washed several times with hot water and, then ether, finally dried in vacuo. Then good quality crystals (I)were obtained in a 1:1 mixture of ethanol and n-hexane.

Refinement top

The hydrogen atoms were located with the help of difference fourier maps. Hydrogen atoms for C7, C6 were positioned geometrically and refined using a riding model.

The end group of N-Et was disordered and modelled with the help of part command. The major component i.e. N3–C10–C11 is depicted in the ORTEP diagram. since this group is diordered over two positions, isotropic refinement is done for these 3 atoms. SADI and DFIX commands were used to model the disordered atoms. The hydrogen atoms were fixed for these atoms.

There are two reflections missing from the fcf file according to check cif which may be at high angle beyond the limiting sphere and not possible for recording despite the fact the data was recollected with another crystal.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
