چکیده
The title mol-ecule, C(8)H(6)BrN, is almost planar (r.m.s. deviation for the non-H atoms = 0.008 Å). In the crystal, weak π-π stacking inter-actions [centroid-centroid separations = 3.782 (2) and 3.919 (2) Å] generate [100] columns of mol-ecules.

Synthesis and Antimicrobial Profile of Newer Schiff Bases and Thiazolidinone Derivatives
Esterification of p-bromo-m-cresol led to formation of 2-(4-bromo-3-methylphenoxy)acetate (1). 2-(4-Bromo-3-methyl phenoxy)acetohydrazide (2) is derived from Compound (1) by hydrazination. Compound (2) was reacted with different aromatic aldehydes to yield N-(substituted benzylidiene)-2-(4-bromo-3-methyl phenoxy)acetamide(3a-c). Cyclization of compound (3a-c) with thioglycolic acid yielded 2-(4...

The title compound, C18H13Br3N2S2, was obtained via the reaction of N-bromo-succinamide with 5,6-dimethyl-2-(thio-phen-2-yl)-1-[(thio-phen-2-yl)meth-yl]-1H-benzimidazole. The compound exhibits rotational disorder of the 5-bromo-thio-phen-2-yl substituent with a refined major:minor occupancy ratio of 0.876 (7):0.124 (7). The 5-bromo-thio-phen-2-yl mean plane is canted to the benzimidazole plane ...
