Comment top

Many nicotine insecticide derivatives have been reported showing various biological activities, e.g. thiacloprid (Jeschke et al., 2002). The title compound (I) was synthesized as an intermediate for the synthesis of nicotine insecticides (Hense et al., 2002). As an important intermediate for the syntesis of insecticides, we report here the crystal structure of (I).

In (I) (Fig. 1), main bond (C—C,C—N,S—C) lengths are normal and in a good agreement with those reported previously (Dupont et al., 1995). Torsion angles of the thiazole ring are small [C4—N2—C3—S1, 6.52 (3)°, C1—S1—C3—N1, 9.95 (2)° and C2—N1—C3—S1, 7.98 (3)°] and thiazole ring is almost planar as the maximum and minimum deviations are 0.188Å and 0.042Å respectively. In the thiazole ring, the dihedral angle between plane A (C1/C2/C3/C4) and plane B (S1/N1/N2/C3) is 5.5 (3)°. The molecule contains a nitrile group, with an CN distance of 1.158 (1) Å, which indicates substantial triple bond character (Allen et al., 1987). Recently, compounds containing the thiazolidin-2-yl-cyanamide group have attracted much interest because compounds containing a thiazole ring system are well known as efficient insecticides (Hense, et al., 2002). The structure is stabilized by hydrogen bonds of N—H···N type.

Experimental top

Cyano-dimethyl dithiocarbamate 14.6 g (0.1 mol) was dissolved in 35 ml ethanol with stirrer and 2-amino-ethanethiol 11.4 g (0.1 mol) was slowly added to the mixture while maintaining the temperature at 303–313 K. After three hours, ethanol was removed under reduced pressure to give title compounds 11.2 g, yield 88%. (Jeschke, et al.,2002). Single crystals suitable for X-ray measurement were obtained by recrystallization from the mixture of acetone and methanol at room temperature.

Refinement top

All H atoms were placed in calculated positions, with C—H = 0.97 Å and N—H = 0.86 Å, and included in the final cycles of refinement using a riding model, with Uiso(H) = 1.2Ueq(C, N).

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.
