- Non-Traditional Coordination in the Complexes of 2-[2-hydroxy(2-Ntosylamino) phenyl] and 2-[2-hydroxyazomethine)]-1-alkylbenzimidazoles A.S. Burlov L.I. Kuznetsova D.A. Garnovskii N.V. Volbushko Boris I. Kharisov A.D. Garnovskii L.M. Blanco Multidisciplinaria (Ciencias Naturales y Exactas) Non adducts traditional coordination transition metal complexes In this paper the formation of molecular complexes (adducts)on the basis of benzimidazole derivatives is reported. The way of localizationof the coordination bond in the synthesized compounds is alsosuggested. The synthesis of the adducts (LH)m · MCln (m = 1, 2; n = 2,4) is carried out by the interaction of typical chelating ligands 2-hydroxy-(N-tosylamino)phenylbenzazoles or hydroxyazomethines of 1-alkyl-2-aminobenzimidazole (LH) with copper, zinc, palladium, tin andtitanium chlorides (MCln). The IR, UV and luminescence studies showthat non-traditional coordinations of the ligands take place in the synthesizedcomplexes. It is suggested that the ligands exist in the complexes,probably, in the quinonoid tautomeric form, connected to the metalatom through the nitrogen atom of pyridinic type and/or oxygen atom ofphenolic fragment of the ligand systems. It is concluded that, in additionto well-known standard metal chelates, the adducts with completelyconserved ligand system (LH) could be also formed on the basis of thetypical chelating ligands above mentioned. 1999 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47543501 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.5 Vol.43
