Based On The Pyridine Class Schiff Alkali Metal Synthesis And Structural Chemistry Research

In this thesis, five reduced salicylaldehyde aminopyridine and three paradoximeSchiff bases have been synthesized and used to react with silver salts through thesolution reaction, thus forming eleven silver complexes with diverse0-D,1-D and2-Darchitectures. Meanwhile, three organic supramolecules were also obtained in thepresence of NO₃^-and ClO4-anions. These ligands and complexes were all characterizedby IR, PL and single crystal X-ray diffraction. Structural analyses indicated that thethree supramolecules were all presented2-D layer motif with the assistance of N-H…Oand O-H…O hydrogen bonding interactions. In silver complexes, the H atom of thehydroxyl group played important roles to the coordination modes of the reduced Schiffbases. Usually, the intact hydroxyl group resulted in the monodentate mode ofheterocyclic nitrogen atom, while the deprotonated hydroxyl group led to the co-bindingmode of N and O atoms. Different inorganic anions and binding modes of paradoximesled to the formation of silver complexes with diverse0-D,1-D and2-D structures, inwhich the μ1-mode was prone to form0-D structure and the μ2and μ4-mode were proneto form1-D and2-D structures. In addition, the reduced pyridine Schiff bases,especially the NO₃^-induced organic supramolecules, presented strong luminescentemissions.
