U disertaciji je ispitana termička stabilnost pet kompleksa prelaznih metala (Cu, Ni i Zn) sa anjonima aromatičnih polikarboksilnih kiselina: ftalne (pht), izoftalne (ipht) i piromelitne (pyr) kiseline i različitim aminskim ligandima, kao što su etilendiamin (en), bipiridin (bipy) i 2,2'-dipiridilamin (dipya). Razmatrani kompleksi [Cu2(bipy)2(pht)2]·4H2O, Na2[Cu(pht)2]·2H2O, K2[Cu(pht)2]·2H2O, [Zn(dipya)(ipht)]n i [Ni2(en)2(H2O)6(pyr)]·4H2O sintetisani su reakcijom izmene liganada. Strukture kompleksa detaljno su opisane zajedno sa uporednom analizom strukturnih karakteristika. Posebna pažnja posvećena je načinu koordinacije odgovarajućeg polikarboksilato-jona i konformaciji karboksilat-grupa koji uslovljavaju različitu dimenzionalnost (0 – 2D) ispitivanih materijala...
Thermal stability of five transition metal (Cu, Ni and Zn) complexes containing the anions of aromatic polycarboxylic acids: phthalic (pht), isophthalic (ipht) and pyromellitic acid (pyr), and different amine ligands such as ethylenediamine (en), bipyridine (bipy) and 2,2'-dipyridylamine (dipya) was investigated. The examined complexes [Cu2(bipy)2(pht)2]·4H2O, Na2[Cu(pht)2]·2H2O, K2[Cu(pht)2]·2H2O, [Zn(dipya)(ipht)]n and [Ni2(en)2(H2O)6(pyr)]·4H2O were synthesized by ligand exchange reaction. Structures of the complexes are described in detail together with a comparative analysis of structural characteristics. Special attention has been devoted to the coordination mode of the corresponding polycarboxylato ion and the conformation of the carboxylate groups which cause the different dimensionality (0 – 2D) of the investigated materials...
