Özet
Two triphenylamine derivatives bearing 4-aminobenzoic acid and 5-aminoisophthalic acid were synthesized. Then, the prepared triphenylamine derivatives were reacted with two new Cr(III) complexes involving tetradenta Schiff bases N,N-bis(salicylidene)ethylenediamine or bis(salicylidene)-o-phenylenediamine. The structures of these compounds were characterized by elemental analysis, FT-IR, TG, H-1 NMR, and C-13 NMR techniques and magnetic susceptibility measurement. The complexes can also be characterized as low-spin distorted octahedral Cr(III) bridged by carboxylic acids. The carboxylic acids play a role as bridges for weak antiferromagnetic intramolecular exchange. Also, the UV spectra of these derivatives revealed that the maximum wavelengths of the complexes are shifted, compared with the ligands.
