Source of material

All reagents and solvents were used as obtained commercially and without further purification. 4-Diethylaminobenzaldehyde (0.177 g, 1 mmol) and 4-chlorobenzohydrazide (0.170 g, 1 mmol) were stirred in ethanol (20 mL). The mixture was refluxed for 3 h to give a clear yellow solution, then cooled to room temperature, and the resulting yellow compound was filtered, washed three with ethanol. Yellow block-shaped crystals of the title compound were obtained by slow evaporation of an ethanol solution in air after 10 days.

Experimental details

One ethyl group is disordered over two sites in a 0.5:0.5 ratio. All H-atoms were placed in calculated positions and treated as riding: C—H = 0.93 or 0.97 Å, N—H = 0.86 Å with Uiso(H) = 1.2 Ueq(parent C, N-atom) and 1.5 Ueq(C35).

Discussion

Schiff base compounds have been of great interest for many years. They play an important role in the development of coordination chemistry related to catalytic [1], pharmacological [2], antitumor activity [3] and as fluorescent sensors [4]. As an extension of work on the structural characterization of Schiff base compounds [5, 6], we here report the crystal structure of the Schiff base compound (E)-4-chloro-N′-(4-(diethylamino)benzylidene). The asymmetric unit of the title compound consists of two crystallographically independent molecules (Figure). In both independent molecules, the C = N bond adopt E configurations. The central moiety in both molcules is not exactly planar with torsion angles C7—N1—N2—C8 and C25—N4—N5—C26 of 172.0(4)° and 178.3(4)°, respectively. The dihedral angles between the benzene rings mean planes is 45.1(1)° and 169.0(1)°, respectively.
