(Received 3 October 2013; accepted 4 October 2013; online 9 October 2013)

The title compound, C9H8N2OS, crystallizes with two mol­ecules (A and B) in the asymmetric unit. The dihedral angles between the mean planes of the 1,3-benzo­thia­zol-2-yl ring system and the acetamide group are 2.7 (4) (mol­ecule A) and 7.2 (2) Å (mol­ecule B). In the crystal, pairs of N—H⋯N hydrogen bonds link the A and B mol­ecules into dimers, generating R22(8) loops. The dimers stack along [100].

Comment top

In continuation of our work on the synthesis of acetamide derivatives (Jasinski et al. 2013), we report herein the crystal structure of the title compound, C9H8N2OS, (I). Some of the related crystal structures of similar acetamide derivatives include, N-(3-chloro-4-fluorophenyl)acetamide, N-(4-bromophenyl)-2-(naphthalen-1- yl)acetamide and N-(3,5-dichlorophenyl)-2-(naphthalen-1-yl)acetamide (Fun et al. 2011a,b, 2012).

The title compound, (I) crystallizes with two independent molecules (A & B) in the asymmetric unit (Fig.1). The dihedral angle between the mean planes of the 1,3-benzothiazol-2-yl ring and the acetamide group is 2.7 (4)° (A) and 7.2 (2)Å (B),(Fig. 2). In the crystal, N—H···N hydrogen bonds forming R22(8) graph set motifs which link the molecules into dimers, which stack along [100].

Experimental top

2-Aminobenzothiazole (1 mmol) were dissolved in a 30 ml acetic acid and it was refluxed for 3 hrs (Fig.3). The reaction mixture was cooled and poured into ice cold water. The precipitate obtained was obtained by filtration and recrystallized in ethanol. Colorless blocks were grown from methanol solution by the slow evaporation method and was used as such for X-ray studies (M.P.: 453-455 K).

Refinement top

All of the H atoms were placed in their calculated positions and then refined using the riding model with Atom—H lengths of 0.93Å (CH), 0.96Å (CH3) or 0.86Å (NH). Isotropic displacement parameters for these atoms were set to 1.2 (CH, NH) or 1.5 (CH3) times Ueq of the parent atom. Idealised methyl were refined as rotating groups.

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