文摘

A new one-dimensional silver(I) coordination polymer [Ag(¦Ì-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(¦Ì-bpfb)(ClO₄)]_n (2), [Ag(¦Ì-bpfb)(SCN)]_n (3) and [Ag(¦Ì-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.
