3-Chloro-6-[(E)-2-(1-phenyl-ethyl-idene)hydrazin-yl]pyridazine.

ABSTRACT: Two independent mol-ecules are present in the asymmetric unit of the title compound, C(12)H(11)ClN(4), (Z' = 2): the dihedral angles between the phenyl and pyridizine rings are 8.35?(10) and 37.64?(6)°. In the crystal, the two mol-ecules form inversion dimers with R(2) (2)(8) ring motifs through inter-molecular N-H?N hydrogen bonds. The crystal structure is stabilized by ?-? inter-actions between the pyridazine rings of symmetry-related molecules. In one of the independent mol-ecules, the centroid-centroid separations are 3.6927?(13) and 3.7961?(13)?Å, whereas in the other, the separations are 3.6909?(13) and 3.9059?(13)?Å.

Two independent mol-ecules are present in the asymmetric unit of the title compound, C(12)H(11)ClN(4), (Z' = 2): the dihedral angles between the phenyl and pyridizine rings are 8.35 (10) and 37.64 (6)°. In the crystal, the two mol-ecules form inversion dimers with R(2) (2)(8) ring motifs through inter-molecular N-H⋯N hydrogen bonds. The crystal structure is stabilized by π-π inter-actions between the pyridazine rings of symmetry-related molecules. In one of the independent mol-ecules, the centro  ...[more]
