In order to studies the effects of various samples of [Ag2(pta)(H2O)]n (1), [H2pta = phthalic acid] coordination polymer, as new precursors with different morphologies, calcination and thermal decomposing in oleic acid of six samples, which were synthesized previously, were carried out. The obtained radiuses were characterized by X-ray powder diffraction and scanning electron microscopy. Silver nanoparticles, microparticles, microporous spongy structure, thin microporous film, mixture of nanosheets and nanoparticles and agglomerated structures of them were obtained during these processes. For about half of the samples, we observed that calcination is more effective than thermal decomposition in oleic acid.
