Organic single crystals that combine mechanical flexibility and optical properties are important for developing flexible devices, but examples of such remain scarce. Both activity depend on the underlying crystal packing nature intermolecular interactions present in solid state. Hence, both can be expected to tunable by small chemical modifications organic molecule. By incorporating a chlorine ...

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 ...

The title compound, C(14)H(10)Br(2)N(2)O(2), was synthesized by the reaction of 5-bromo-salicylaldehyde with an equimolar quantity of 3-bromo-benzohydrazide in methanol. The dihedral angle between the two benzene rings is 10.5 (4)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds to form chains parallel to the c axis, and an intra-molecular O-H⋯N int...
