dc.description.abstractExtensive research work was carried out in past few decades to synthesize new compounds with extended structures by employing various organic linkers and metals. A large number of potential applications of these coordination polymer materials were explored as it contains both inorganic metals as well as organic molecules. The large open pores of coordination polymer compounds were explored for applications such as absorption, separation, and catalysis etc. whereas the framework part provides a model system to study physical properties such as magnetism, luminescence, ferroelectricity etc. We were mainly interested in designing new magnetic materials with extended structures which is the primary objective of this thesis. To study this a systematic investigations are carried out with azide bridged copper(II) compounds. Azide is a versatile ligand which possesses a large number of bridging modes. On the other hand, the coordination flexibility offered by the copper centres makes it to possess diverse coordination number (4-6) as well as geometry. Copper-azide compounds were synthesized at room temperature and the structure was determined using single-crystal X-ray diffraction studies. Structure and magnetic behavior of the copper-azide compounds were studied and discussed here in this thesis. Further, we have studied selective absorption and separation of aliphatic nitrile compounds by employing a two-dimensional interdigitated coordination polymer. In addition, transformation studies of a Ni5 cluster to a Ni9 cluster have also been carried out. Chapter 1 of this thesis presents a brief overview of azide based compounds and summarizes important copper-azide compounds and their magnetic behavior. In chapter 2, synthesis, structure, and magnetic behavior of two-dimensional copper-azide based compounds have been presented. Field dependent magnetic studies were also carried out for all the compounds. Chapter 3 presents the synthesis, structure, and magnetic behavior of copper-azide compounds where 1,2-diaminopropane was employed as a site blocking agent. In chapter 4, the synthesis, structure, and magnetic behavior of two isostructural three-dimensional copper-azides are presented. In chapter 5, synthesis, structure, and magnetic behavior of the azide based one and two-dimensional compounds are presented. Chapter 6 presents synthesis and structure of a two-dimensional inter-digitated coordination polymer compounds. The selective absorption and separation of aliphatic nitriles were also presented in this chapter. In chapter 7, synthesis, structure, and magnetic behavior of Ni clusters are presented. A transformation study to convert a Ni5 cluster to Ni9 cluster was also carried out and presented in this chapter.en_US
