A mixture of salicylaldehyde and freshly distilled thioglycollic acid in 1:1.2 mole ratio was dissolved by heating on a water bath and let stand two days. The product was washed with water and recrystallized.
H atoms bonded to O were isotropically refined and the other H atoms were positioned geometrically (C—H=0.93–0.98 Å) and allowed to ride on their parent atoms, with 1.2 Ueq(C).

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. |

In coordination chemistry, the acylhydrazone ligands attracted the chemists due to their potential behaviour in magnetochemistry (Yu et al., 2010; Guo et al., 2010). The choice of N-acylhydrazonyl derivatives was suggested by publications indicating that compounds with such groups might have anti-tumoural activities (Rollas & Kucukguzel 2007). Against this background and to ascertain the molecular structure of title compound, the crystallographic study has been carried out.
The ORTEP plot of the molecule is shown in Fig. 1. The bond lengths involving the sulfur atoms in methyl sulfanyl groups [S1—C7=] 1.821 (2) Å, [S1—C10=] 1.799 (2) Å, [S2—C7=] 1.830 (2) Å and [S2—C8=] 1.794 (2) Å are comparable with the standard values of 1.82 Å reported in the literature (Allen et al., 1987).
The crystal structure is stabilized by C—H···O and O—H···O types of intra and intermolecular interactions which form a three demensional network shown in Fig. 2. The intermolecular O1—H1···O4 and O2—H2A···O1 hydrogen bonds form two different R22(18) dimers. The molecules at O5 (x, y, z) and O3 (-x + 1, -y, -z) are linked through an intermolecular O5—H5A···O3 hydrogen bond into cyclic centrosymmetric R22(20) dimer (Bernstein et al., 1995).
