摘要：

omega-Isonitrosoacetophenone (1), phenylglyoxime (2), chlorophenylglyoxime (1), dopaminophenylglyoxime (3) and [(salen/saloph)Fe](2)O (4) have been synthesized as described in the literature procedure. [Fe(III)(salen/saloph)dopaminophenylglyoxime)] (starting complexes) have been synthesized from dopaminophenylglyoxime and tetradentate schiff bases which contain dinuclear Fe(III) oxygen-bridges N,N'-bis(salicylidene)ethylenediamine (salenH(2)) and bis(salicylidene)-o-phenylenediamine (salophH(2)). The new heterotrinuclear complexes have been obtained from starting complexes and Co(II), Ni(II), Cu(II) salts. Then, heterotrinuclear vic-dioxime complexes containing BF2+ capped have been synthesized. The complexes have been characterized as low-spin distorted octahedral Fe(III) bridged by o-hydroxyphenolic groups. The o-hydroxyphenolic groups play a role as bridges for weak antiferromagnetic intramolecular exchange. The structure of dioxime and its complexes were identified by using elemental analysis, ICP-AES, H-1-NMR and IR spectral data.
