Preparation of silver nanostructure from silver(I) coordination polymer and fabrication of nano silver(I) bromide by reverse micelles technique

A new one-dimensional silver(I) coordination polymer, [Ag(mu-bpfb)(NO(3))](n) (1); bpfb =N,N'-bis(4-pyridylformamide)-1,4-benzene, has been synthesized and characterized by IR, (1)H NMR and (13)C NMR spectroscopy. The single crystal X-ray data show that the silver(I) 10 coordination polymer grows into a three-dimensional network by hydrogen bonding and pi-pi stacking interactions. Compound 1 with nanorod morphology was also prepared by sonochemical method. The cetyltrimethylammonium bromide (CTAB) as a cationic surfactant was used in reverse micelles technique to obtain spongy silver(I) bromide nanoparticles from compound 1. Also, different silver nanoparticles have been prepared via direct calcination at 673 K and thermal decomposition in oleic acid from compound 1. The nanostructures of [Ag(mu-bpfb)(NO(3))](n) (1), silver and silver(I) bromide were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray (EDAX) analysis. Thermal stability of compound 1 in both bulk and nano-sized form was studied by thermal gravimetric (TG) and differential thermal (DT) analyses. (C) 2010 Elsevier B.V. All rights reserved.
