Özet

Ligand complexes ([M(salen/salophen)](2)O, [M(saldeta)]Cl shortened as LC, M=Cr(III), Mn(III) or Fe(III)), have been synthesized. 2,4,6-tris(4-formylphenoxy)-1,3,5-triazine (3) was synthesized with the reaction of p-hydroxybenzaldehyde (2) and cyanuric chloride (1). 2,4,6-tris(4-(4-carboxyphenylimino)phenoxy)-1,3,5-triazine (5) was synthesized with the reaction of 2,4,6-tris(4-formylphenoxy)-1,3,5-triazine (3) and 4-aminobenzoic acid (4). 2,4,6-tris(4-(4-carboxyphenylimino)phenoxy)-1,3,5-triazine was treated with SOCl2 in CH3CN, and 2,4,6-tris(4-(4-chloroformylphenylimino)phenoxy)-1,3,5-triazine (6) was obtained. 2,4,6-tris(4-(4-chloroformylphenylimino)phenoxy)-1,3,5-triazine was reacted with 4-aminobenzoic acid or 4-hydroxbenzoic acid in CH3CN, and 2,4,6-tris(4-(4-(4-carboxyphenylamido)phenylimino)phenoxy)-1,3,5-triazine (8) and 2,4,6-tris(4-(4-(4-carboxyphenylformato)phenylimino)phenoxy)-1,3,5-triazine (9) were obtained. s-Triazine cored tripodal trinuclear Schiff bases complexes were synthesized with the reaction of 8 and/or 9 and ligand complexes. The complexes have been characterized as low-spin (S=1/2) distorted octahedral Fe(III)Salen/Salophen, low-spin (S=1) distorted octahedral Mn(III)Salen/Salophen, high-spin (S=5/2) distorted octahedral Fe(III)Saldeta, high-spin (S=2) distorted octahedral Mn(III)Saldeta and (S=3/2) distorted octahedral Cr(III)Salen/Salophen/Saldeta bridged by COO- groups. The structure of all ligand and complexes were identified by using elemental analysis, thermal analyses (TGA-DTG), magnetic susceptibility, ESI-MS, ICP-AES, UV-Vis, H-1-NMR, C-13-NMR and FT-IR spectral data.
