N'-Benzyl-idene-2-chloro-N-(4-chloro-phen-yl)acetohydrazide.

In the title compound, C15H12Cl2N2O, the atoms not making up the chloro-benzene ring are approximately coplanar (r.m.s.

Synthesis, characterization and molecular docking studies of some new 1,3,4-oxadiazolines bearing 6-methylpyridine moiety for antimicrobial property.

A new series of 3-acetyl-2-aryl-2H/methyl-5-[3-(6-methylpyridinyl)]-2,3-dihydro-[1,3,4]-oxadiazole derivatives were synthesized from 6-methyl nicotinate through a multistep reaction sequence. The structures of newly synthesized compounds were established on the basis of elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data. Three dimensional structure of the compound 5f was further confirmed by single crystal X-ray analysis.

N'-[(E)-3-Chloro-2-fluoro-benzyl-idene]-6-methyl-nicotinohydrazide monohydrate.

The title compound, C(14)H(11)ClFN(3)O·H(2)O, exists in an E conformation with respect to the N=C bond. The pyridine ring forms a dihedral angle of 5.00 (9)° with the benzene ring.
