dc.description.abstractKobalt(II), mangan(II), nikel(II), çinko(II) ve bakır(II) p-hidroksibenzoatların kafein komplekslerinin genel formülleri aşağıdaki gibidir.[Co(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OI[Mn(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OII[Ni(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OIII[Zn(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OIV[Cu(HOC6H4COO)2(H2O)3].(C8H10N4O2)2.4H2OVKomplekslerin FT-IR, UV spektroskopisi, TG-DTA, ayrıca molar iletkenlik ve çözünürlük özellikleri incelendi.TG-DTG termik analiz metodu kullanılarak 20 – 1000oC sıcaklık aralığında azot atmosferinde komplekslerin termal özellikleri incelendi. Komplekslerin termal bozunma sonucu ilk basamakta su moleküllerini, ikinci basamakta kafein moleküllerini kaybederler. Termal bozunma sonucunda son ürün olarak CoO (I) MnO2 (II), NiO (III), ZnO (IV), CuO (V) oluştuğu gözlemlendi.X ışını kırınımı yöntemiyle I – IV komplekslerinin yapısı aydınlatıldı.
dc.description.abstractThe general formulas of the caffeine complexes of p-hydroxybenzoates cobalt (II), manganese (II), nickel (II), zinc (II) and copper (II) are as follows. [Co(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OI [Mn(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OII[Ni(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OIII[Zn(HOC6H4COO)2(H2O)4].(C8H10N4O2)2.8H2OIV[Cu(HOC6H4COO)2(H2O)3].(C8H10N4O2)2.4H2OVThe complexes FT-IR, UV spectroscopy, TG-DTA, molar conductivity and solubility properties were also investigated.Thermal properties of the complexes have been studied by using TG-DTG thermal analysis method in nitrogen atmosphere, the temperature range 20 oC–1000oC. Caffeine molecules in the second step, water molecules in the first step of thermal destruction result of complexes , loses. It was observed to occur, CoO (I), MnO2 (II), NiO (III), ZnO (IV), CuO (V) as last product in thermal decomposition.The structure of the I - IV complexes have been recorded on by X-ray diffraction method.en_US
