Abstract
The reversible crystal-to-crystal transformations of a 1D lead(II) coordination polymer with the ligand 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene (4-bpdh), from [Pb(4-bpdh)Br-2](n) (1) to intermediate [Pb(4-bpdh)(Br)(NO3)](n) (2) and [Pb(4-bpdh)(NO3)(2)(H2O)](n) (3) by a solid state anion-replacement processes under mechanochemical reactions, have been studied. The reversible solid state structural transformation of compound 1 to compound 2 and then 3 by anion replacement have been verified by PXRD and IR measurements. PbBr2, PbBr(OH), Pb3O2Br2 and PbO nanoparticles were obtained by the thermal decomposition of compounds 1, 2 and 3 in oleic acid at 180 degrees C in an air atmosphere, respectively. These nanoparticles were characterized by powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM).
