Summary

N-(o-hydroxybenzylidene)-2-aminobenzimidazole (HL) andN-(o-hydroxybenzylidene)-2(2′-aminophenyl)benzimidazole (HL′) react with CoX2 (X=Cl, Br, or NCS) and FeCl3 yielding complexes of general formulae [Co(HL)2X2], [Co(HL′)2X2], [FeCl2(HL)2] [FeCl4], and [FeCl2(HL′)2][FeCl4]. Moreover, it was possible to isolate the complexes [Co(HL)Br2] [Co(L)Cl] and [Co(L′)Cl]. The complexes were characterized by elemental analyses, i.r. and electronic spectroscopies and conductivity and magnetic measurements at different temperatures.
