Abstract In order to highlight the presentation of this thesis and to provide more detailed investigations of coordination polymer, the thesis was separated into three chapters according to the sequence of the work. This dissertation concentrated solely on the synthesis, and properties of bis-pyridyl-bis-amide and divalent metal-based coordination polymer. Chapter I At the outset, the basic aspects of coordination chemistry including ligands and different metal ions is introduced, including a brief discussion regarding coordination polymers. Chapter II Three isomorphous one-dimensional (1D) Hg(II) halide coordination polymers constructed from angular 4,4ˊ-oxybis(N-(pyridine-3-yl)benzamide) (L1), [Hg(L1)X2H2O]n(X = Cl, 1; Br, 2; I, 3), have been structurally characterized by using single-crystal X-ray crystallography. Complexes 1 – 3 were highly stable in water and various organic solvents at room temperature up to 7 days. Mechanochemical method has been used to reproduce 1–3, which was achieved only in MeOH and EtOH. Complexes 1 – 3 display luminescent properties and their potentials toward the detection of Fe3+ ion are discussed. Chapter III Eight coordination polymers constructed from divalent metal salts, using bis-pyriydl-bis amide ligands with different substituted dicarboxylic acid are reported. They were structurally characterized by single-crystal X-ray diffraction. The eight coordination polymers are [Co(L2)(5-ter-IPA)(H2O)2]n (L2 = N1,N4-bis(pyridin-3-ylmethyl)terephthalamide) ; 5-tert-H2IPA = 5-tert-butylisophthalic acid), 4, {[Co(L2)(5-NO2-IPA)]2H2O}n (5-NO2-H2IPA = 5-nitroisophthalic acid), 5, {[Co(L2)0.5(5-NH2-IPA)]CH3OH}n (5-NH2-H2IPA =5-aminoisophthalic acid), 6, {[Co(L2)(MBA)]2H2O}n (H2MBA = diphenylmethane-4,4’–dicarboxylic acid), 7, {[Co(L2)(SDA)]H2O}n (H2SDA = 4,4-sulfonyldibenzoic acid), 8, {[Co2(L2)2(1,4-NDC)2(H2O)2]5H2O}n (1,4-H2NDC = naphthalene-1,4-dicarboxylic acid), 9, {[Cd(L2)(1,4-NDC)(H2O)]2H2O}n, 10, and {[Zn2(L2)2(1,4-NDC)2]2H2O}n, 11. The photodegradation of organic dyes using complexes 4 – 6 is also reported.
