The 21H25N3O2S·0.5C2H3N, contains two independent molecules with almost similar structural properties along with a solvent molecule of acetonitrile. The compound exists in the E conformation with respect to the azomethine C=N double bond. The hydrazinecarbothioamide moieties in both independent molecules are almost planar [maximum deviations of 0.013 (2) and 0.007 (2) Å]. The molecular conformation is stabilized in each case by an intramolecular N—H⋯N hydrogen bond. In the crystal, pairs of N—H⋯S hydrogen bonds link each of the independent molecules into inversion dimers. The dimers are interconnected by means of three C—H⋯π interactions.

The preparation of the compound involves a two step process (Jacob & Kurup, 2012). In the first step, cyclohexylisothiocyanate (15 mmol, 2 ml) in 15 ml methanol and hydrazine hydrate (90 mmol, 4.3 ml) in 15 ml methanol were mixed and the resulting solution was stirred for an hour when the colourless product, N(4)-cyclohexylthiosemicarbazide formed was filtered, washed with methanol and dried in vacuo. In the second step, 4-benzyloxy-2-hydroxybenzaldehyde (0.2283 g, 1 mmol), dissolved in 15 ml acetonitrile was added to a solution of N(4)-cyclohexylthiosemicarbazide in 10 ml acetonitrile and the reaction mixture was refluxed for 3 hrs in acidic medium. The resultant solution was kept for one week to give yellow crystals of the compound (yield 51.59%, 0.1978 g)

All H atoms on C were placed in calculated positions, guided by difference maps, with C—H bond distances of 0.93 Å. H atoms were assigned Uiso(H) values of 1.2Ueq (carrier). H atoms of N—H bonds were located from difference maps and the bond distances are restrained to 0.88±0.01 Å. Omitted owing to bad disagreement was (0 0 2). The phenolic H atoms were located from difference maps and the O–H bond distances were restrained to 0.84±0.01 Å.

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. |

Thiosemicarbazones are important class of compounds due to their antimicrobial activity (Joseph et al., 2004). They are also found to act as turn on fluorescent sensors for fluoride anion (Kumar et al., 2013). These compounds are important due to their ability to show versatile coordination abilities in complexes (Sreekanth et al., 2004). Here we present a new N4-substituted thioemicarbazone with interesting structural properties.
The asymmetric unit of the title compound consists of two independent molecules of the thiosemicarbazone and one acetonitrile molecule giving an overall ratio of thiosemicarbazone to acetonitrile to 2:1. The compound crystallizes into triclinic space group P-1. The geometric parameters of each molecule are almost identical. The molecules adopt E configuration with respect to C14—N1 and C35—N4 bonds which is confirmed by the C14/N1/N2/C15 and C35/N4/N5/C36 torsion angles of -177.55 (17)° and 175.50 (18)° respectively (Fig.1). The N1/N2/C15/S1 and N4/N5/C36/S2 torsion angles of 171.78 (3)° and -173.54 (4)° suggest that the thionyl atom S1 of the first molecule and S2 of the second molecule are located trans to azomethine nitrogens N1 and N4 respectively. The torsion angles -6.0 (3)° and 5.2 (3)° for N1/N2/C15/N3 and N4/N5/C36/N6 respectively confirm the cis configuration of N1 with respect to N3 and N4 with respect to N6.
The C14—N1 and C35—N4 bond distances [1.281 (2) and 1.278 (2) Å] are close to that of formal C═N bond [1.284 (3) Å] (Seena et al., 2006). Similarly the C15—S1 and C36—S2 bond distances [1.6835 (17) Å and 1.6824 (17) Å] are also close to that of formal C═S bond [1.68 (3) Å] (Jacob & Kurup, 2012). The hydrazine carbothioamide moieties in both molecules are almost planar with maximum deviation of 0.013 (2) Å for atom C15 and 0.007 (2) Å for C36 respectively from their least square planes. The cyclohexyl rings in both the molecules adopt chair conformation. The least square plane calculations show that the rings C1–C6/C8–C13 in one molecule and C22–C27/C29–C34 in the other molecule are twisted with a dihedral angles of 82.93 (120)° and 88.59 (12)° respectively.
Whilst one the molecules in the asymmetric unit has only one intramolecular hydrogen bond of the type O—H···N with D···A distance 2.696 (2) Å and one N—H···S type intermolecular hydrogen bonding interaction with D···A distance 3.3046 (18) Å, the other molecule has two types of intramolecular hydrogen bonds of O—H···N and N—H···N with D···A distances 2.680 (2) and 2.655 (3) Å respectively along with one type of N—H···S intermolecular hydrogen bonding with D···A distance 3.3495 (18) Å (Table 1). All these intermolecular interactions present in two asymmetric molecules build two centrosymmetric dimers in the crystal lattice (Fig 2). These dimers are interconnected by means of three C—H···π interactions with H···π distances of 2.95, 2.87 and 2.84 Å (Fig. 3). Fig 4 shows the packing of molecules along crystallographic a axis.
