Three dinuclear copper(II) complexes [Cu-2(pdc)(2)(dpyo)(H2O)(2)](n) (1), ([Cu-2(pdc)(2)(dabco)(H2O)(2)]center dot 2H(2)O), (2) and {[Cu-2(pdc)(2)(bpp) (H2O)(2)]center dot 2H(2)O}(n) (3) [pdc, pyridine-2,6-dicarboxylate; dpyo, 4,4'-dipyridyl-N,N'-dioxide; dabco, 1,4-diazabicyclo[2.2.2]octane and bpp, 1,3-bis(4-pyridyl)propane] have been synthesized and structurally characterized by single crystal X-ray diffraction analysis and thermal study. Hydrogen bonding interactions, formed by coordinated and lattice water molecules, lead to a supramolecular architecture in all of them. Thermogravimetric analyses reveal that the complexes undergo reversible deaquation-reaquation process.
