Synthesis and characterization of new Mn (ııı) complexes of Schiff bases derived from some amino acids and indole-3- carboxaldehyde

İndol-3-karboksaldehit ile DL-glisin ve DL-alanin'nin kondensasyonundan hazırlanan amino asit-Schiff bazlarının yeni Mn(III) kompleksleri sentezlendi ve yapılan; element analizi, iletkenlik ölçümleri, elektronik ve IR spektrumları ile karakterize edildi. Amino asit-Schif bazlarının yapılan 1H ve 13C-NMR spektrumları ile aydınlatıldı. Burada amino asit-Schiff bazlarının tek değerli iki dişli ligant olarak davrandığı sonucuna vanldı. Mn(III) kompleksleri için oktahedral yapılar önerildi.

Bazı amino asit ve indol-3-karboksaldehit'ten hazırlanan Schiff bazlarının yeni Mn(III) komplekslerinin sentezi ve karakterizasyonu

New complexes of Mn(III) with amino acid-Schiff bases derived from the condensation of indole-3-carboxaldehyde with DL-glycine and DL-alanine were synthesized and characterized by elemental analyses, conductance, electronic and IR spectra. The 1H and 13C-NMR spectra of amino acid-Schiff bases were elucidated. It is concluded that the amino acid-Schiff bases to the metal ion as a monovalent bidendate ligand. Octahedral structure have been suggested for Mn(III) complexes.
