Synthesis and Characterization of Zn(II) Complexes Containing 5-Sulfosalicylic Acid and 2--Amino-4-substituepyridine Derivatives

Öz

Four new Zn(II) complexes {[Zn(Hssal)(X)2(H2O)2] (H3ssal: 5-sulfosalicylic acid, X = 2-amino-4-methylpyridine (1) for 5, 2-amino-3-nitro-4-methylpyridine (2) for 6 and (HX)2[Zn(Hssal)2(H2O)2], X = 2-amino-4,6-dimethylpyridine (3) for 7, 2-amino 4-chloropyridine (4) for 8} were synthesized and its structures were proposed by elemental analysis, AAS, IR, molar conductivity and magnetic susceptibility. The results of IR and conductivity analyses, it was observed that 5 and 6 metal complexes were non-ionic, while 7 and 8 metal complexes were 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.

Dört yeni Zn(II) kompleksleri {[Zn(Hssal)(X)2(H2O)2] {H3ssal: 5-sülfosalisilik asit, X = 5 için 2-amino-4-metilpiridin (1), 6 için 2-amino-3-nitro-4-metilpiridin (2) ve (HX)2[Zn(Hssal)2(H2O)2] X = 7 için 2-amino-4,6-dimetilpiridin (3), 8 için 2-amino-4-kloropiridin (4)} sentezlendi ve yapıları element analiz, AAS, IR, molar iletkenlik ve manyetik duyarlılık ile önerildi. IR ve iletkenlik analizleri sonucunda 5 ve 6 nolu metal komplekslerinin iyonik olmadığı, 7 ve 8 nolu metal komplekslerinin ise iyonik olduğu gözlenmiştir. Bu sonuçları AAS ve elementel analiz 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
