Abstract: The synthesis and characterization of complexes of stoichiometry Cu(Xsal)2(H2O)2 for X = 3-MeO and 4-MeO and Cu(Xsal)2(H2O) for X = 3-Me and 4-Me (where 3-MeOsal = 3-methoxysalicylate, 4-MeOsal = 4-methoxysalicylate, 3-Mesal = 3-methylsalicylate and 4-Mesal = 4-methylsalicylate) are reported. The composition of all complexes has been determined by elemental analysis and their ligand coordination mode and stereochemistry have been determined by electronic, infrared and EPR spectroscopy. The photoreactivity of prepared complexes in DMSO (DMSO = dimethylsulfoxid) solutions at room temperature have been studied too. For complexes of composition Cu(4-MeOsal)2(H2O)2 and Cu(4-Mesal)2(H2O) some spectral changes registered after irradiation with light (λirr = 366 nm).
Keywords: copper complexes, salicylato ligand, EPR spectra, molecular structure, photoreactivity
