dc.description.abstract |
Three new dinuclear copper(II) complexes of 2-mino-3-methylpyridine has been prepared and characterized by spectroscopic, magnetic and elemental analysis. Complex [Cu-2(2-amino-3-methylpyridine)(4)(OCH3)(2)] (NO3)(2) were characterized magnetically by magnetic susceptometer. The magnetic susceptibility of powdered [Cu-2(2-amino-3-methylpyridine)(4)(OCH3)(2)](NO3)(2) has been examined in the range of 5 to 270 K. The dimer exhibits an antiferromagnetic exchange interaction The best fit to the Bleaney-Bowers equation was obtained yielding 2J = 133 cm(-1) with g = 2.02 and p = 2.58 x 10(2) for the complex in c.g.s. units. The dinuclear complexes are ESR silent in solid state and only a weak signal of monomeric impurities is observed Frozen solution ESR spectra suggests that the complexes dissociate when dissolved in DMF or DMSO. |
