Abstract:	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.
