摘要
Three dinuclear copper(II) complexes [Cu2(pdc)2(dpyo)(H2O)2]n (1), {[Cu2(pdc)2(dabco)(H2O)2]·2H2O}n (2) and {[Cu2(pdc)2(bpp)(H2O)2]·2H2O}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.
