Hydrogen and halogen bonding patterns and π–π aromatic interactions of some 6,7-disubstituted 1,3-benzothiazoles studied by X-ray diffraction and DFT calculations

6-Iodo-2-methyl-1,3-benzothiazole

The title compound, C₈H₆INS, is essentially planar, the largest deviation from the mean plane being for the I atom [0.075 (3) Å]. The crystal structure is mainly stabilized by inter­molecular C—I⋯N halogen bonds, forming zigzag supra­molecular chains in [10]. Relatively short off-set π–π contacts [centroid–centroid distance = 3.758 (2) Å] between the thia­zole rings of inversion-related mol­ecules link neighbouring chains and provide the secondary inter­actions for building the crystal structure.
