   ABSTRACT

In the recent years, coordination polymers (CPs) with entangled architectures have a great deal of attention not only due to their potential applications in fields such as gas adsorption and separation but also due to their diverse structural topologies. To design and synthesize CPs with the desired structure and specified properties, many structural and experimental factors play important roles in the self-assembly process of CPs. It has been determined that coordination polymers exhibit gas storage, ion exchange, catalysis and fluorescence properties. Its use as a sensor in gas separation and purification is very important as it can contribute to the  control and reduction of environmental pollution. They are also used in the pharmaceutical and cosmetic industries.[1]

In this study, three new two dimensional (2D) coordination polymers were synthesized by hydrothermal method using 3,3-tetramethyleneglutaric acid (1,1-cyclopentanediacetic acid) (H2tmg) and neutral ligands containing 1,2-bis((1H-imidazol-1-yl)methyl)benzene (obix). The structures of [Co(μ-tmg)(μ-obix)]n (1), [Zn(μ-tmg)(μ-obix)]n (2) and [Cd(μ-tmg)(μ-obix)]n (3)  complexes were characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction analysis methods. Furthermore, thermal, photoluminescence and topological analyses were performed. Optical band gaps were investigated with diffuse reflectance spectroscopy.
