Özet
2,4,6-tris(4-hydroxybenzimino)-1,3,5-triazine [ 1,2] (III) have been synthesized by the reaction of 1 equiv melamine and three equiv 4-hydroxybenzaldehyde, and characterized by means of elemental analysis, H-1-NMR (nuclear magnetic resonance spectroscopy), Fourier transform infrared (FTIR) spectrscopy, liquid chromatography-mass spectroscopy (LC-MS). L (IV) has been synthesized by the reaction of one equiv (III) and three equiv 4-(thiophenoxy) phenyloxylohydroxymoyl chloride (II), and characterized by means of the same methods. Then, four novel trinuclear Fe(III) and Cr(III) complexes involving tetradentate Schiff bases N,N'-bis(salicylidene)ethylenediamine-(salenH(2)) or bis(salicylidene)-o-phenylenediamine-(salophen H-2) with L (IV) have been synthesized and characterized by means of elemental analysis, FTIR spectrscopy, LC-MS, thermal analyses. The metal ratios of the prepared complexes have been determined using AAS. The aim of the present study is synthesis of novel tridirectional-trinuclear systems and to present their effects on magnetic behavior of [salenFe(III)], [salophenFe(III)], [salenCr(III)], and [salophenCr(III)] capped complexes. The complexes have also been characterized as low-spin distorted octahedral Fe(III) and Cr(III) bridged by keton-oxime group.
