Experimental Crystal data

R factor = 0.063; wR factor = 0.186; data-to-parameter ratio = 13.5. In the title molecule, C15H12Cl2N4O, the two benzene rings are inclined at a dihedral angle of 14.5 (2). In the crystal, intermolecular N—H O hydrogen bonds link molecules into chains propagated in [001]. Related literature For related structures, see: Meyers et al. (1995); Li et al. (2008)
