Özet

2-(2-Hydroxyphenyl)-5-R-1-1H-benzimidazoles [R-1=H ((LM)-M-1), CH3 ((LH)-H-2), Cl ((LH)-H-3), NO2 ((LH)-H-4)], 2-(2-Hydroxy-5-R-2-phenyl)-1H-benzimidazoles [R-2=Br ((LH)-H-5), NO2 ((LH)-H-6)] and their Zn(NO3)(2) complexes were synthesized, characterized by elemental analysis, molar conductivity, IR and H-1-NMR spectra. (LH)-H-1, (LH)-H-2, (LH)-H-4 and (LH)-H-6 give a complex with Zn(NO3)(2) in general formula Zn(L-n)(2); however, (LH)-H-3 and (LH)-H-5 complexes are in [Zn(L-n)(2)](HNO3)(2) form. The substituent effect on the characteristic of the ligands and the complexes was investigated.
