Bu çalışmada2-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 ligandların (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.  Ligandların 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.
