5-[(4-Bromophenyl)diazenyl]-2-{2-[1-(1H-indol-3-yl)ethylidene]hydrazinyl}-4-methylthiazole dimethylformamide hemisolvate

The asymmetric unit of the title compound, 2C20H17BrN6S·C3H7NO, comprises two molecules of the thiazole derivative and one molecule of dimethylformamide (DMF) solvent. The twist angles between the planes through the bromophenyl, methylthiazolyl and indolyl groups are 10.1 (1) and 44.2 (1)°, respectively, for one molecule and 11.3 (1) and 1.6 (1)° for the other. In the crystal, N—H...N hydrogen bonds link four of the main molecules into tetramers. N—H...O bonds involving the DMF solvent molecule also occur
