(E)-1-[1-(3-Chloro-phen-yl)ethyl-idene]-2-(2,4-dinitro-phen-yl)hydrazine.


ABSTRACT: There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(14)H(11)ClN(4)O(4), with the same E conformation about the C=N double bond. The mol-ecules are approximately planar, with a dihedral angle between the benzene rings of 10.24?(12)° in one mol-ecule and 4.73?(12)° in the other. In both mol-ecules, the ortho-nitro groups of the 2,4-dinitro-phenyl units are coplanar to their bound benzene rings, whereas the para-nitro groups are slightly twisted. In each mol-ecule, intra-molecular N-H?O hydrogen bonds generate S(6) ring motifs. In the crystal, mol-ecules are linked by weak C-H?O inter-actions into sheets parallel to the (-102) plane. These sheets are stacked by ?-? inter-actions, with centroid-centroid distances of 3.7008?(14) and 3.7459?(14)?Å. A Cl?O short contact [3.111?(2)?Å] is observed.
