Abstract

The title compound, C(16)H(13)NOS, was prepared by alkyl-ation of 1-(benzothia-zol-2-yl)propan-2-one with propargyl bromide. The asymmetric unit contains two mol-ecules that are crystallographically independent but linked to each other by non-classical C-H⋯O hydrogen bonds, building up a dimeric substructure. The benzothia-zole rings are essentially planar with maximum deviations of 0.005 (1) and 0.007 (2) Å for the N atoms. Although the two mol-ecules have similar bond distances and angles, they slightly differ in the orientation of the benzothia-zole ring with respect to the two propargyl groups and the acetonyl unit . In the crystal, inter-molecular C-H⋯O inter-actions link the dimeric subunits into a two-dimensional array in the bc plane.

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.
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.
