摘要:
Three new complexes {[Cu(dpdapt)(Hhbd)] center dot 6H(2)O}(n), (1) (dpdapt = N,N'-di(2-pyridyl)-2,4-diamino-6-phenyl-1,3,5-triazine, Hhbd = 2-hydroxybutanedioicate dianion), [Cu(dpdaPt)(SO4)]center dot 2H(2)O (2) and [Cu(dpdapt)(oxa)] center dot H2O (3) (oxa = oxalate dianion) have been synthesized and structurally characterized. The non-covalent interactions of pi-pi stacking and hydrogen bonding extend complexes 1-3 into supramolecular architectures, where 1 self-assembles into a ID polymeric chain by dicarboxylate bridges and exhibits a 3D framework with 1D open channels, while complexes 2 and 3 display 2D wavelike networks. Interestingly, in 1, the host framework encapsulates hexameric water clusters that are connected into ID arrays by supramolecular association along the ID open channels. The UV/vis, IR spectra, fluorescence and TG analysis for complexes 1, 2 and 3 are also discussed. (c) 2006 Elsevier Ltd. All rights reserved.
