Synthesis, spectroscopic characterization, and crystal structures of Schiff bases derived from nicotinic hydrazide

Résumé

Two Schiff bases were prepared from nicotinic hydrazide and o-vanillin (H2L 1) (1) or salicylaldehyde (H2L 2) (3) and were characterized by elemental analysis, 1 H and 13 C NMR and IR spectroscopic studies. Compound were protonated in ethanol-nitric acid solution and gave compound [(H3L 1). (NO3)] (2). The compound (2) crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 7.2005 (3) Å, b = 8.8914 (4) Å, c = 22.6392 (9) Å, = 96.753 (2)°, V = 1439.36 (11) Å3, Z = 4, R1 = 0.059 and wR2 = 0.037. The compound (3) crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 26.615 (4) Å, b = 11.3366 (14) Å, c = 8.1903 (9) Å, = 98.814 (3)°, V = 2442.0 (5) Å3, Z = 8, R1 = 0.085 and wR2 = 0.141. Both molecules present inter and intramolecular hydrogen bonds which consolidate the structures in three-dimensional networks.
