Abstract |
세자리 schiff base 리간드로서 salicylidene imino-o-thiobenzene은 salicylaldehyde와 o-aminothiolbenzene을 Duff reaction 시킴으로써 합성하였으며 이 리간드와 Cu(Ⅱ), Ni(Ⅱ), 및 Zn(Ⅱ) 이온들과의 반응으로서 새로운 착물 Cu(Ⅱ)[C13H9ONS]·3H2O, 및 Ni(Ⅱ)[C13H9ONS]·3H2O, Zn(Ⅱ)[C13H9ONS]·3H2O들을 합성하였다. 이 착물들은 가시부 자외선스펙트럼, 적외선스펙트럼, TGA, DTA 및 원소분석측정에 의하여 리간드와 금속은 1:1 몰비로 착물을 이루며 Cu(Ⅱ) 착물은 1수화물 4배위 결합착물이고 Ni(Ⅱ), 및 Zn(Ⅱ) 착물은 3수화물, 6배위 결합의 착물임을 알아보았다. The tridentate schiff base, salicylidene imino-o-thiolbenzene, has been synthetized from salicylaldehyde and o-amino thiolbenzene by Duff reaction. The schiff base has been reacted with Cu(Ⅱ), Ni(Ⅱ), and Zn(Ⅱ), to form new complexes; Cu(Ⅱ)[C13H9ONS]·H2O, Ni(Ⅱ)[C13H9ONS]·3H2O, and Zn(Ⅱ)[C13H9ONS]·3H2O. It appears that the Cu(Ⅱ)-complex has tetra-coordinated configuration with the schiff base and one molecule of water, while the Ni(Ⅱ) and Zn(Ⅱ)-complexes have hexacoordinated configuration with the schiff base and three molecules of water. The mole ratio of tridentate schiff base ligand to metals was 1:1. These complexes have been identified by infrared spectra, visible spectra, TGA, DTA and elemental analysis. |
