Abstract
Bu tez çalışması iki kısımdan oluşmaktadır: Birinci kısımdapirazinamid ligantı içeren [Cd(PZA)2Ni(CN)4], [Zn(PZA)2Ni(CN)4], [Hg(PZA)2Cl2]n, [Cd(PZA)2Cl2]n, (PZAH)2[CdCl4], [Zn(PZA)2Cl2]n, [Ni(PZA)2Cl2]n, [Co(PZA)2Cl2]n, kompleksleri sentezlendi. Sentezlenen bu komplekslere Cu2+geçiş metal iyonu katkılandırılarak toz kristalleri elde edildi ve oda sıcaklığında EPR spektrumları kaydedildi.Cu2+iyonu katkılandırılanbu komplekslerden Ni(CN)4 içeren [Zn(PZA)2Ni(CN)4] kompleksindeparamanyetik iyonun yerel simetrisinin rombiksimetride olduğu buna mukabil [Cd(PZA)2Ni(CN)4] kompleksinde ise eksensel simetride olduğu belirlendi.Cu2+iyonu katkılandırılan ve Ni(CN)4içermeyen diğerkomplekslerin tamamında paramanyetik iyonunun yerel simetrisinin eksensel simetride olduğu belirlendi. İkinci kısımda ise yine pirazinamid içeren[Cd(PZA)2Ni(CN)4], [Co(PZA)2Ni(CN)4]ve [Hg(PZA)2Cl2]n komplekslerineMn2+iyonu katkılandırılarak toz kristallerin EPR spektrumları oda sıcaklığında kaydedildi. Spektrumların incelenmesi neticesindeparamanyetik iyonunun yerel simetrisinin tüm kompleksler için kübik simetride olduğu belirlendi.
This thesis study includes two parts: In the first part the complexes including the pyrazinamide ligand of, [Zn(PZA)2Ni(CN)4], [Hg(PZA)2Cl2], [Cd(PZA)2Cl2], [CdCl2((PZA)HCl)2], [Zn(PZA)2Cl2], [Ni(PZA)2Cl2], [Co(PZA)2Cl2], were synthesized. Polycrystallines were obtained which synthesized these complexes with Cu2+ions doped and recorded EPR spectra at room temperature. Of the complexes having Ni(CN)4in the Cu2+ doped [Zn(PZA)2Ni(CN)4] complex the local symmetry of the paramagnetic ion was determined as rhombic while in [Cd(PZA)2Ni(CN)4]complex as axial. For the other complexes not having Ni(CN)4and doped with the Cu2+ ion, the local symmetry of the paramagnetic center was determined as axially symmetric. In the second part of the study, Mn2+ions were doped to [Cd(PZA)2Ni(CN)4], [Co(PZA)2Ni(CN)4], [Hg(PZA)2Cl2] complexes and the EPR spectra of the powder samples were recorded at room temperature.The local symmetry of the paramagnetic center was identified as cubic as a result of the inspection of the EPR spectra.
