The edbea ligand display different coordination modes in the present complexes. For example, 1 and 2 it acts a tridentate way, while it exhibits a mu-N/O bidentate bridging mode between the copper centers in 3. On the other hand, the geometry of 4 eight-coordinated by two tetradentate edbea ligands is the bicapped trigonal prism structure in which S(degrees) value is the smallest. The EPR spectrum of 3 showed that the local geometry of Cu(II) ion has an elongated rhombic coordination. Complexes 1 and 3 exhibited a paramagnetic behavior as expected, but complex 1 displayed an antiferromagnetic interaction at low temperatures.eninfo:eu-repo/semantics/closedAccess2,2′-(Ethylenedioxy)bis(ethylamine)Thermal analysisCrystal structuresMagnetic propertiesSaccharinDeprotonated saccharinCopper(ii) complexesCrystallizationCu2+ChemistryCrystallography2Bridging modeComplex 1Coordination modesCopper centersCrystals structuresEthylamineSaccharinateX-ray diffraction methodArticle0003378838000042-s2.0-84899903716243078https://doi.org/10.1016/j.poly.2014.03.056Chemistry, inorganic & nuclearCrystallographyComplex; Palladium; 2-Phenylpyridine
