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, 1 H‐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. J. Heterocyclic Chem., (2011).
