Abstract
The title compound, C12H8Cl2N4O, is non-planar, the dihedral angle formed between the pendant pyrazine and benzene rings being 12.55 (11)°. An intramolecular N-HN hydrogen bond occurs. The amide groups self-associate via N-HO hydrogen bonding, forming supramolecular chains with base vector [101], which are stabilized by C-HO contacts. C-HN interactions are formed orthogonal to the chains.Keywords: None Document Type: Research Article DOI: http://dx.doi.org/10.1107/S1600536809053343 Publication date: 1 de Janeiro de 2010
