Figure 2 Crystal packing of the title compound with inter­molecular N—H⋯O hydrogen bonds, π—π and halogen—halogen inter­actions shown as dashed lines. H atoms not involved in inter­molecular inter­actions have been omitted for clarity. Cg1 and Cg2 are the centroids of the phenyl and pyridazine rings, respectively. (Symmetry codes: i) 1 − x, 1 − y, −z; ii) x, 0.5 − y, [{1\over 2}] + z; iii) −x, −[{1\over 2}] + y, 1.5 − z; iv) 1 − x, 1 − y, 1 − z; v) −x, 1 − y, 1 − z; vi) −x, [{1\over 2}] + y, 1.5 − z; vii) x, 1.5 − y, [{1\over 2}] + z; viii) 1 − x, [{1\over 2}] + y, 0.5 − z; ix) 1 − x, −[{1\over 2}] + y, 0.5 − z).
