Abstract.

The crystal structure of N-( p-nitrobenzylidene)-3-chloro-4-fluoroaniline (II) has been determined by X-ray structure analysis. This belongs to a class of benzylidene anilines. The structure was solved by direct method. The molecular packing of the non-planar molecules are held by Van der Waals and F....H7, O ....Cl, F .... F and N .... H interactions.

Keywords: Benzylidene aniline; X-ray crystallography; intermolecular interactions.
