Abstract

This thesis includes two parts discussing the synthesis, structure andintermolecular interactions of metal complexes containing polydentate ligands. Part I. The reactions of the unsymmetrical N-Phenyl-N′-cyano-formamidine (HPhCNF) ligand with Cd(NO3)2 · 4H2O and Co(NO3)2 · 6H2O affordedtwo complexes of the type M(HPhCNF)2(NO3)2(THF), (M = Cd, 1 ; M =Co), 2 which were characterized by single-crystal X-ray diffraction method and elemental analyses.Both the metal center of complexes 1 and 2 adopt pentagonal bipyramidal geometry. The metal atoms were bonded to two nitrogen atoms of cyano group, four chealting nitrate oxygen atoms, and one oxygen atom of THF solvent group. In these two complexes, C-H---O and N-H---O hydrogen bonds were found to link the molecules. Part II. The reactions of 2-aminotkiazole (2-AT) with AgClO4, AgNO3,Ag2SO4, and Zn(OAc)2 · 2H2O afforded four new complexes of the types of [Ag(2AT)2ClO4], 3 [Ag(2AT)2NO3], 4 [Ag2(2AT)2(SO4)][Ag2(2AT)2](SO4)] · 2(CH3OH), 5 and Zn(OAc)2(2AT)2, 6. Their crystal structures were characterized by single-crystal X-ray diffraction method and elementalanalyses. In complexes 3 and 4, the silver metal centers adopt linear geometry that were bonded to two nitrogen atoms of 2-AT. The molecules adopting linear geometry were interlinked through N-H---O hydrogen bonds. Molecules in complexes 5 were linked through extensive Ag---S, Ag---O, Ag---Ag, S---S, S---O, O---O, hydrogen bondings, and π – π staking interactions. In complex 6, the zinc metal centers were bonded to two nitrogen atoms of two different 2-AT groups, one monodentate acetate and one chealting acetate anion, to form a distorted square pyramidal geometry. The molecules were linked through N-H---O hydrogen bonds and S---S interaction. In compounds 7 and 8, the protonated 2-Amino-2-thiazoline cations, [H(2A2T)]+ were interacted with nitrate and perchlorate anions through hydrogen bonds, forming 1-D hydrogen-bonded tapes. The eight complexes were characterized by single-crystal X-ray diffraction method and elemental analyses.
