Sonochemical syntheses of one-dimensional silver(I) supramolecular polymer: A precursor for preparation of silver nanostructure

Nano-structures of one-dimensional supramolecular polymer, [Ag(Me-8-HqH)(Me-8-Hq)](n) (1) [Me-8-HqH = 2-methyl-8-hydroxyquinoline], have been synthesized by the reaction of Me-8-HqH and AgNO3 by sonochemical process. The single-crystal X-ray data of compound 1 shows that both two Ag-I ions are chelated by two Me-8-HqH and Me-8-Hq(-) molecules. Coordination number of Ag-I ions in compound 1 is four and they have AgO2N2 coordination sphere. The Ag-I complexes in 1 are linked to each other via hydrogen bonding and form a supramolecular chain structure. Thermal decomposition of compound 1 nanostructure in oleic acid results in formation of silver nano-structure. These nano-structures were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The thermal stability of compound 1 was studied by thermogravimetric (TG) and differential thermal analyses (DTA). (C) 2014 Elsevier B.V. All rights reserved.
