چکیده
The amide group in the title compound, C(7)H(6)ClN(3)O(3), is significantly twisted out of the plane of the benzene ring [C-C-C-O = 34.2 (5)°] whereas the nitro group is almost co-planar [O-N-C-C = 4.0 (5)°] with the ring. Intra-molecular N-H⋯O and N-H⋯Cl hydrogen bonds occur. In the crystal, the mol-ecules are linked by N-H⋯O hydrogen bonds, generating layers propagating in the ab plane.

In the title compound, C(13)H(8)ClN(3)O(5), the dihedral angle between the two aromatic rings is 70.74 (6)°. The nitro groups of the Cl-substituted and benzamide benzene rings are twisted by 2.6 (1) and 31.3 (2)°, respectively. The crystal packing shows inter-molecular C-H⋯O hydrogen bonds that link mol-ecules into sheets stacked along [010].

Two novel 3-amino-5-(4-choloro-2-phenoxyphenyl)-4H-1,2,4-triazole derivatives were prepared and their anticonvulsant activity was measured by evaluation of the ability of these compounds to protect mice against convulsion induced by lethal doses of pentylenetetrazole (PTZ). Diazepam (Sigma) was considered as a positive control drug with anticonvulsant effect [ED50 = 1.2 (0.5-1.9) mg/Kg]. Amongs...
