Abstract he present thesis includes three main chapters with Arabic and English summaries. The data were gathered in (20 Tables) and represented in (59 Figures), and (14 Schemes). Also, the results were listed in (133 reference), which focuses on the literature survey on the previous researches, and the characterization of some ligands and their metal chelates containing thiourea and nicotinic acid, as well as dipropylenetriamine. Chapter 1: Introduction This chapter describes the importance of nicotinic acid with its derivatives; dipropylenetriamine with its metal complexes along with thiourea, and their uses. Also, this chapter concerned with a scientific literature survey on nicotinic acid derivatives, thiourea and dipropylenetriamine compounds and their complexes together with their biological activity. Chapter 2: Experimental This chapter includes three main parts: Materials and Instruments This section gives details of chemicals used for the preparation of all new compounds in thesis. Also, it restricts all instruments used for characterization the structures of the ligand, and metal complexes |
