Abstract

The synthesis, spectroscopic and magnetic characterization of a series of new alkoxo bridged binuclear copper (II) compounds is described. All complexes have the general formula [Cu (µ-OR)(L)2]2(ClO4)2 • x H2O, in which µ-OR = CH3O , C2H5O or C3H7O , L = 2 amino 4 methylpyridine (abbreviated A4PIC) and 2 amino 5 methylpyridine ( abbreviated A5PIC). The title compounds all consist of dinuclear units with alkoxo bridging group. All complexes have been synthesized in one-step reaction, and characterized by elemental analysis, FTIR and electronic spectra and by magnetic properties. The compounds exhibit strong antiferromagnetic interaction at room temperature. The UV-Vis spectra shows three absorption bands, which can be attributed to d-d transition of copper (II) ion, ligand --> metal charge transiton and π --> π transition of the ligand. The IR spectra indicate Cu2O2 ring vibrations in 500-570 cm-1 range. The magnetic properties of the [Cu2(A5PIC)4)(O -CH3)2](ClO4)2 complex has been investigated in the 5-265 K range and a singlet triplet energy gap (-2J) of 126 cm-1 was observed.
