Self-assembly reactions of copper (II) ions, dicarboxylate (adipate or terephthalate) and terminal ligands (4,4′-bipyridine or phenanthroline) yielded three hydroxy-bridged Cu(II) cluster complexes: [Cu(phen)(OH)(H 2O)] 2·(C 8H 4O 4)·8H 2O ( 1), [Cu 4(bpy) 4(OH) 4(H 2O) 2]·(C 8H 4O 4) 2·6H 2O ( 2) and [Cu 6(bpy) 6(OH) 6(H 2O) 2]·(C 6H 8O 4) 3·23H 2O ( 3) (phen = phenanthroline, bpy = 2,2′-bipyridine, C 8H 6O 4= terephthalic acid, C 6H 10O 4= adipic acid). Single crystal X-ray diffraction analyses reveal that complex 1is a discrete dinuclear Cu 2O 2motif, 2presents a discrete chairlike tetranuclear copper(II) Cu 4O 4core formed by two Cu 2O 2units, and 3assumes a discrete hexameric copper(II) Cu 6O 6cluster consisting of three Cu 2O 2units. The polynuclear structures are generated from the Cu(II) ions linked by the µ 2- and/or µ 3-OH groups. In 1− 3, all Cu(II) ions show square pyramidal coordination geometry, and the dicarboxylate ions act as counteranions to keep the whole structure neutral. Thermogravimetric analyses (TGA) and magnetic properties of 1− 3were studied, respectively.
