Keywords: Schiff base | 2-thiophenecarboxaldehyde | N-(2-thienylmethylene)methanamine | antibacterial activity
ABSTRACT
(Received 26 July, revised 10 December 2007)Two new Schiff bases containing olefinic linkages have been synthesized by condensing aliphatic diamines with dicinnamoylmethane under specified conditions. The existence of these compounds predominantly in the intramolecularly hydrogen bonded keto-enamine form was well demonstrated by their IR, 1H-NMR and mass spectral data. Dibasic tetradentate N2O2 coordination of the compounds in their [ML] complexes (M = Ni(II), Cu(II) and Zn(II)) was established on the basis of analytical and spectral data.
