چکیده
In the title mol-ecule, C(16)H(11)N(5), the mean planes of the quinoxaline and indazole fragments form a dihedral angle of 10.62 (5)°. In the crystal, weak inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into zigzag chains extending in the [001] direction. The crystal packing also exhibits π-π inter-actions [centroid-centroid distances of 3.7080 (2) and 3.8220 (5) Å], which form stacks of the mol-ecules parallel to the a axis.

Anticoccidial activities of 7-bromo-N-(2-imidazolidinylidene)-1H-indazol-6-amine and other alpha 2 adrenergic agonists.
Activity against the coccidial pathogen Eimeria tenella in chickens has been discovered among alpha 2 adrenergic agonists. The clonidine analog 7-bromo-N-(2-imidazolidinylidene)-1H-indazol-6-amine was active in feed at 7.5 ppm, a concentration similar to the use levels of potent commercial agents, e.g., maduramicin. Additional alpha 2 agonists were also found to have anticoccidial activity, for...
متن کاملN,N′-Bis[(E)-quinoxalin-2-ylmethylidene]ethane-1,2-diamine
In the mol-ecule of the title compound, C(20)H(16)N(6), the central C-C bond lies on a crystallographic inversion centre. The quinoxalidine ring is nearly planar, with a maximum deviation of 0.021 (2) Å from the mean plane. The crystal structure is stabilized by inter-molecular C-H⋯N inter-actions, leading to the formation of a layer-like structure, which extends along the a axis.
