Four new tetradentate ligands 1-(Thiophen-2-yl)-N-(4-{(E)-[(thiophen-2-yl)methyl]iminomethyl}benzylidene)methanamine (1), 2-(Thiophen-2-yl)-N-(4-{(E )-[2-(thiophen-2-yl)ethyl]iminomethyl}benzylidene)ethanamine (2), 1,4 Bis[(2pyridylethyl)iminomethyl]benzene (3) and 1,4-Bis[(2pyridylethyl)iminoethyl]benzene (4) have been prepared by a 1:2 molar condensation of an aromatic dialdehyde (terephthalaldehyde) with thiophen-2-ylmethanamine, 2-(thiophen-2-yl)ethanamine, pyridin-2-ylmethanamine and 2-(pyridin-2-yl)ethanamine. The ligands were characterised on the basis of their elemental analysis, FT-IR spectroscopy, 1H, 13C NMR, ESI-mass spectrometry and for ligands 1, 2 and 4 also by X-ray diffraction. The crystal structures reveal that the ligands exist as discrete molecules with an average C-N bond distance of 1.2656 Å which is consistent with C=N double bonding.
