Bazı karboksilik asitlerden elde edilen proton transfer tuzlarının ve Cu (II) komplekslerinin sentezi ve karakterizasyonu

Abstract

Bu çalışmada 2-amino-3-metilpiridinin (amp), 1,4-pirazin-2,3-dikarboksilik asit (H₂pyzdc) ve tiyoglikolik asit (Htga) ile reaksiyonundan sırasıyla proton transfer tuzları (Hamp)⁺(Hpyzdc)^- (1)  ve (Hamp)⁺(tga)^- (2) elde edilmiştir. Daha sonra elde edilen tuzların (1 ve 2)  Cu(CH₃COO)₂.2H₂O ile reaksiyonundan ise metal kompleksleri  (Hamp)₂[Cu₃(pyzdc)₄(H₂O)₆].8H₂O (3) ve (Hamp)₂[Cu(tga)₂(H₂O)₂].2H₂O (4)  sentezlenmiştir.  Tuzların yapıları ¹H ve ¹³C-NMR, FT-IR ve UV-Vis  spekroskopileri ve elementel analiz yöntemleri  ile aydınlatılmıştır. Tek kristali elde edilemeyen komplekslerin yapıları ise FT-IR, UV-Vis, ICP-OES, manyetik duyarlılık ve elementel analiz tekniklerinden elde edilen sonuçların değerlendirilmesiyle önerilmiştir.

Synthesis and characterization of proton transfer salts and Cu(II) complexes derived from some carboxylic acids

Abstract

In this study  the proton transfer salts (Hamp)⁺(Hpyzdc)^- (1)  and (Hamp)⁺(tga)^- (2) have been obtained from the reaction of 2-amino-3-methylpyridine (amp) with 1,4-pyrazine-2,3-dicarboxylic acid (H₂pyzdc) and thioglycolic acid (Htga), respectively. Subsequent reaction of the salts (1 and 2) with [Cu(CH₃COO)]₂.2H₂O leads to the formation of metal complexes (Hamp)₂[Cu₃(pyzdc)₄(H₂O)₆].8H₂O (3) and (Hamp)₂[Cu(tga)₂(H₂O)₂].2H₂O (4). The structures of salts were characterized by  ¹H and  ¹³C-NMR, FT-IR and UV-Vis spectra and elemental analysis methods.  The structures of complexes which cannot obtain single crystals have been proposed by evaluating the results obtained from FT-IR, UV-Vis, ICP-OES, magnetic susceptibility and elemental analysis techniques.
