Abstract
- Three new coordination polymers, [Cu(butca)0.5(bipy)(H2O)]n · 2nH2O (1), [Zn(H2butca) (phen)(H2O)]n · nH2O (2), and [Cd(H2chhca)0.5(phen)(H2O)]n · 2nH2O (3) (H4butca =1,2,3,4-butanetetracarboxylic acid, H6chhca = 1,2,3,4,5,6-cyclohexanehexacarboxylic acid), were prepared and characterized by EA, IR, TG, and X-ray crystallography. Complex 1 is a 1-D double-chain coordination polymer in which tetradentate butca4- coordinates to four Cu(II) ions through four monodentate carboxylates. Complex 2 is a 1-D chain with tridentate H2butca2- coordinating to two Zn(II) ions through monodentate and chelating carboxylates. Complex 3 is a 1-D double-chain coordination polymer. H2chhca4- is octadentate coordinating to four Cd(II) ions through four chelating carboxylates. Hydrogen bonds and π-π stacking interactions play important roles in the formation of supramolecular architectures. The thermal stabilities of 1-3 show dehydrated coordination polymers are thermally stable in the range 260-400°C. [ABSTRACT FROM AUTHOR]
