The exobidentate coordination mode of pyrazolato ligands in 1-4 was inferred on basis of IR spectroscopic evidences. TG investigations indicated that the introduction of substituents at the 4 position in the pyrazolyl moiety into coordination polymers do not affect significantly their thermal stability, whereas at the 3 and 5 position reduced the stability of the main chain. Metal palladium was the final product of the thermal decompositions, which was identified by X-ray powder diffraction.789-792engcoordination polymersDTApalladium(II)pyrazolatesTGArtigo10.1007/s10973-006-7863-0WOS:000244823700035Acesso restrito33002239708144487471310113999140792767705365081985341388134171610000-0002-0057-79640000-0003-1574-681X
