The title compound, C23H24FN3O, crystallizes with two independent mol-ecules (I and II) in the asymmetric unit. These pairs of mol-ecules are linked to each other as N-H⋯O dimers with an R 2 (2)(10) motif. Furthermore, the crystal structure also exhibits C-H⋯π inter-actions. The atoms of the ethyl group in mol-ecule I are disordered over two sites with an occupancy ratio of 0.817 (6):0.183 (6).
A series of N'-substituted-2-(5-nitrofuran or 5-nitrothiophen-2-yl)-3H-benzo[d]imidazole-5-carbohydrazide derivatives were synthesized and investigated for their abilities to inhibit β-hematin formation, hemoglobin hydrolysis and in vivo for their antimalarial efficacy in rodent Plasmodium berghei. Selected analogues were screened for their antitubercular activity against sensitive MTB H(37)Rv ...
N′-[1-(4-Chlorophenyl)ethylidene]-5-methyl-1-(4-nitrophenyl)-1H-1,2,3-triazole-4-carbohydrazide
In the title compound, C(18)H(15)ClN(6)O(3), the 1,2,3-triazole ring forms dihedral angles of 15.64 (5) and 57.50 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 72.26 (5)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along the b axis. A short O⋯C contact of 2.9972 (13) Å is observed.
