Supporting information
A mixture of the phenyl isothiocyanate (0.1 mol), and piperidine (0.1 mol) was stirred in refluxing ethanol (20 mL) for 4 h to afford the title compound (0.086 mol, yield 86%). Single crystals suitable for X-ray measurements were obtained by recrystallization from ethanol at room temperature.
H atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances = 0.93 - 0.97 Å, and with Uiso=1.2 or 1.5Ueq.

Special details top 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. |

Thioamide have received considerable attention in the literature. They are attractive from several points of view in application (Toshiaki et al., 2003). As part of our search for new thioamide compounds we synthesized the title compound (I), and describe its structure here.
The C6—S1 bond length of 1.7056 (17)Å is comparable with C—S bond [1.688 (2) Å] reported (Cowley et al., 2002). The distance of N1—C6 [1.349 (2) Å] is similar to the distance of reported [1.349 (1) Å] (Casas et al., 2002). The crystal strucure is stabilized by an intermolecular N—H···S hydrogen bond, and weak intramolecular C—H···S and C—H···N hydrogen bonding interactions (Table 1). Fig. 2 shows the intermolecular N—H···S hydrogen bonds between the neighbour molecules in the unit cell.
