Syntheses and structural characterization of two new nanostructured Bi(III) supramolecular polymers via sonochemical method

• Two Bi(III) coordination polymers were prepared and characterized by XRD analyses.
• The nanostructures of these compounds were also synthesized by sonochemical method.
• The nanostructures were characterized by FE-SEM, and XRD analyses.

Two new bismuth(III) coordination supramolecular polymers, {[Bi2(Hbpp)(bpp)(μ-I)2I6](Hbpp)·MeOH}n (1) and [Bi(Hbpp)(Br4)] (2), (bpp = 1,3-di(pyridin-4-yl)propane) were prepared and were structurally characterized by single crystal X-ray diffraction. Single crystalline one-dimensional materials were prepared using a heat gradient applied a solution of the reagents using the branched tube method. The structural determination by single crystal X-ray crystallography shows that compounds 1 and 2 form monoclinic polymers with symmetry space group P21 in the solid state. These new nanostructured Bi(III) supramolecular compounds, {[Bi2(Hbpp)(bpp)(μ-I)2I6](Hbpp)·MeOH} (1) and [Bi(Hbpp)(Br4)] (2), were also synthesized by sonochemical method. The nanostructures were characterized by Field Emission-scanning electron microscopy (FE-SEM), powder X-ray diffraction (PXRD) and IR spectroscopy.
