(2E)-2-[2-(4-Chloro-phen-yl)hydrazin-1-yl-idene]-4,4,4-trifluoro-3-oxobutanal.


ABSTRACT: The title compound, C(10)H(6)ClF(3)N(2)O(2), was synthesized by coupling 4-dimethyl-amino-1,1,1-trifluoro-but-3-en-2-one with 4-chloro-benzene-diazo-nium chloride. It crystallizes with two mol-ecules in the asymmetric unit, which form two similar centrosymmetric dimers via hydrogen bonds. Extensive electron delocalization and intra-molecular N-H?O hydrogen bonds are responsible for a planar conformation of the mol-ecules (maximum deviations = 0.010 and -0.015?Å for the two molecules). In addition to hydrogen bonds, ?-? stacking inter-actions with centroid-centroid distances of 3.604?(2) and 3.583?(2)?Å contribute to the stability of the crystal structure.
