Abstract

Bu çalışmada, dört yeni Zn(II) kompleksleri {(HX)2[Zn(Hssal)2(H2O)2], H3ssal: 5-sülfosalisilik asit, X = 5 için 2-amino-6-metilpiridin (1), 6 için 2-amino-3-etil-6-metilpiridin (2) ve 7 için 2-amino-3-nitro-6-metilpiridin (3)} ve {[Zn(Hssal)(X)2(H2O)2] {X = 8 için 2-amino-3-nitro-6-kloropiridin (4)} elde edildi. Zn(II) komplekslerinin yapıları element analizi, AAS, FT-IR, molar iletkenlik ve manyetik duyarlılık analizleri ile karakterize edildi. IR ve iletkenlik analizleri sonucunda 5-7 metal komplekslerinin iyonik olduğu ve 8 metal kompleksinin ise iyonik olmadığı gözlenmiştir. Bu sonuçları AAS ve elementel analiz testleri de desteklemektedir. Manyetik duyarlılık çalışmalarında Zn(II) (d10) metal komplekslerinin beklendiği gibi eşleşmemiş elektron taşımadıkları gözlenmiştir. Yapılan spektroskopik analiz sonuçlarında tüm komplekslerin (5-8) oktahedral yapıya sahip oldukları önerilmiştir.

Synthesis and Characterization of Zn(II) Complexes of 2-Amino-6-substituepyridine Derivatives and 5-Sulfosalicylic Acid

Abstract

This study, four new Zn(II) complexes {(HX)2[Zn(Hssal)2(H2O)2], (H3ssal: 5-sulfosalicylic acid, X = 2-amino-6-methylpyridine (1) for 5, 2-amino-3-ethyl-6-methylpyridine (2) for 6, 2-amino-3-nitro-6-methylpyridine (3) for 7, and [Zn(Hssal)(X)2(H2O)2], X = 2-amino-3-nitro-6-chloropyridine (4) for 8} were synthesized. The structures of Zn(II) complexes (5-8) were characterized by elemental analysis, AAS, FT-IR, molar conductivity and magnetic susceptibility analyses. The results of IR and conductivity analyses, it was observed that 5-7 metal complexes were ionic, while 8 metal complexes were non-ionic. AAS and elemental analysis tests also support these results. In magnetic susceptibility studies, it was observed that Zn(II) (d10) metal complexes did not carry unpaired electrons as expected. The results of the spectroscopic analysis of complexes 5-8 have an octahedral structure.
