Abstract

In this study; a mixed ligand Cu(II) complex, [Cu(Me2mal)(bpy)(H2O)]∙H2O (Me2mal-2= Dimethylmalonate dianion, bpy=2,2'-bipyridine) was synthesized and characterized experimentally and theoretically by IR, UV and single crystal X-ray diffraction. The complex crystallizes in the orthorhombic system with space group Pnnm. In the complex, the Cu center is coordinated by a Me2mal-2 dianion and a bpy molecule, and the N2O2 exhibits square-planar geometry. The axial position was occupied by the water molecule. The crystal packing of the complex is stabilized by O-H…O hydrogen bonds and  interactions. The contribution of hydrogen bonding and  stacking interactions to crystal packing was also investigated. Theoretical calculations using the DFT method were also carried out in this study. DFT (B3LYP/6-31G) and TD-DFT (B3LYP/LanL2DZ) calculation methods were used to obtain the geometric, vibrational and electronic properties of the synthesized complex and the obtained theoretical calculation results and experimental results are presented comparatively in this study.

Özet

Bu çalışmada; karışık ligantlı Cu(II) kompleksi, [Cu(Me2mal)(bpy)(H2O)]∙H2O (Me2mal-2= Dimetilmalonat dianyonu, bpy=2,2'-bipiridin) sentezlenmiştir. Sentezlenen kompleks IR, UV ve tek kristal X-ışını kırınımı yöntemleri ile deneysel ve kuantum mekaniksel hesaplama yöntemleri kullanılarak teorik olarak karakterize edilmiştir. Kompleks, Pnnm uzay grubunda ortorombik kristal sisteminde kristallenmiştir. Komplekste Cu merkezi; bir Me2mal-2 dianyonu ve bir bpy molekülü tarafından koordine edilmiştir ve N2O2 kare-düzlemsel geometri sergilemektedir. Eksensel pozisyonda ise su molekülü bulunmaktadır. Kompleksin kristal paketlenmesi O-H...O hidrojen bağları ve etkileşimleri ile kararlı bir yapı oluşturmuştur. Çalışmada hidrojen bağlarının ve  istifleme etkileşimlerinin kristal paketlenmeye katkısı da araştırılmıştır. Bu çalışmada DFT yöntemi kullanılarak teorik hesaplamalar da yapılmıştır. Sentezlenen kompleksin geometrik, titreşimsel ve elektronik özelliklerini elde etmek için DFT (B3LYP/6-31G) ve TD-DFT (B3LYP/LanL2DZ) hesaplama yöntemleri kullanılmıştır. Elde edilen teorik hesaplama sonuçları ve deneysel sonuçlar karşılaştırmalı olarak verilmiştir.
