Crystal structure of 1-((1E)-{(E)-2-[(2-hydroxy-naphthalen-1-yl)methyl-idene]hydrazin-1-yl-idene}meth-yl)naphthalen-2-ol.

The complete mol-ecule of the title compound, C22H16N2O2, is generated by a crystallographic inversion centre at the mid-point of the central N-N bond. Two intra-molecular O-H⋯N hydrogen bonds occur.

Synthesis, crystal structures and docking studies of 2,7-diphenyl-1,4-diazepan-5-one derivatives.

Background: 1,4-Diazepine derivatives are the seven membered, nitrogen containing heterocyclic ring systems possessing a wide range of therapeutic applications. 1,4-Diazepines attracted the attention of chemists and druggists due to their biological and medicinal properties, such as antimicrobial, anti-HIV and anticancer activities. Herein, we report the preparation, crystal structure determined by X-ray crystallographic methods and docking of the molecules with the potential target protein NS5B RNA polymerase.

4-(5-Chloro-thio-phen-2-yl)-1,2,3-selenadiazole.

In the title compound, C6H3ClN2SSe, the selenadiazole and chloro-thio-phene rings are almost coplanar [dihedral angle = 5.24 (15)°]. In the crystal, C-H⋯N inter-actions link the mol-ecules into chains extending along the b-axis direction.
