In our continuing efforts to explore the effects of substituent groups of ligands in the formation of supramolecular coordination structures, seven new CuIIcomplexes formulated as [Cu2(L1)4(DMF)2] (1), {[Cu2(L1)4(Hmta)](H2O)0.75}∞(2), [Cu2(L2)4(2,2′-bipy)2] (3), [Cu2(L3)4(H2O)2] (4), [Cu2(L3)4(Hmta)]∞(5), [Cu2(L3)4(Dabco)]∞(6) and [Cu2(L3)4(Pz)]∞(7) with three monocarboxylate ligands bearing different substituent groups HL1–HL3(HL1=phenanthrene-9-carboxylic acid, HL2=2-phenylquinoline-4-carboxylic acid, HL3=adamantane-1-carboxylic acid, Hmta=hexamethylenetetramine, 2,2′-bipy = 2,2′-bipyridine, Dabco=1,4-diazabicyclo[2.2.2] octane and Pz=pyrazine), have been prepared and characterized by X-ray diffraction. In 1, 2 and 4–7, each CuIIion is octahedrally coordinated, and carboxylate acid acts as a syn–syn bridging bidentate ligand. While each CuIIion in 3 is penta-coordinated in a distorted square-pyramidal geometry. 1 and 4 both show a dinuclear paddle-wheel block, while 2, 5, 6 and 7 all exhibit an alternated 1D chain structure between dinuclear paddle-wheel units of the tetracarboxylate type Cu2-(RCO2)4and the bridging auxiliary ligands Hmta, Dabco and Pz. Furthermore, 3 has a carboxylic unidentate and μ1,1-oxo bridging dinuclear structure with the chelating auxiliary ligand 2,2′-bipy. Moreover, complexes 1–6 were characterized by electron paramagnetic resonance (EPR) spectroscopy.
