Silver nanofibers from the nanorods of one-dimensional organometallic coordination polymers

Abstract

A 1D pencil shaped organometallic coordination polymer, [Ag₂(μ₅-TPOAc)₂]_n (1) [TPOAc⁻ = triphenylacetate], has been synthesized and characterized and its structure was determined by X-ray crystallography. There are two types of Ag⁺ ions, which form strong η² Ag2–C π bonds, two weak η¹ Ag1⋯C π interactions and strong Ag–Ag interactions, resulting in the formation of C₂⋯Ag1O₃Ag₂ and Ag2O₃C₂Ag₂ moieties with very interesting structures. In addition we prepared metal coordination nano-polymers (MCNPs) of compound 1 by ultrasonic process where pyrolysis of compound 1 nanorods, as a template, result in silver nanofibers.
