Abstract :
A new one-dimensional silver(I) coordination polymer [Ag(μ-bpfb)(NO3)]n (1), bpfb = N,N′-bis(4-pyridylformamide)-1,4-benzene, has been synthesized and characterized by IR, NMR spectroscopy and single crystal X-ray crystallography. Nanorods compound 1 were obtained by sonochemical process and characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The nitrate ions of compound 1 in nanostructure exchange with perchlorate, thiocyanate and azide anions by the solid state reaction. Three new compounds [Ag(μ-bpfb)(ClO4)]n (2), [Ag(μ-bpfb)(SCN)]n (3) and [Ag(μ-bpfb)(N3)]n (4), were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The silver nanoparticles were obtained from direct calcination of compounds 1–4 nanostructures in an electrical furnace at 673 K.
