Magnetic and spectral properties of adducts of copper(II) chlorobenzoates with substituted piperazines

Adducts of Cu(OOCR)2 (where R = 2-, 3- or 4-ClC 6H4) with saturated substituted piperazines of the type Cu(OOCR)2(L-L)n [where n = 0.5 or 1 and L-L = 1-methylpiperazine (1-MePipz), 1,4-dimethylpiperazine (l,4-Me2Pipz). 2,6-dimethylpiperazine (2,6-Me2Pipz) and 1-phenylpiperazine (1-PhPipz)] have been prepared and characterized by elemental analysis, infrared, electronic reflectance, electron paramagnetic resonance spectral and magnetic moment studies. Three complexes which have room temperature magnetic moment values lower than the spin only values and have room temperature electron paramagnetic resonance spectra corresponding to S = 1, rather than S = 1/2, have been further subjected to magnetic susceptibility and electron paramagnetic resonance spectral measurements at different temperatures to evaluate spin-exchange parameter (-2J = 282-313 cm-1). Based upon the above studies, axially symmetric binuclear structure for complexes of the type Cu(OOCR)2(L-L), polymeric structure containing binuclear units for the Cu(OOCR)2(L-L)0.5 complexes and axially symmetric polymeric square pyramidal or trans-pseudo octahedral structure for complexes of the type Cu(OOCR)2(2,6-Me2Pipz) (R = 2-, 3- and 4-ClC6H4), have been proposed.

Magnetic and spectroscopic characterization of copper(II) chlorobenzoate adducts with substituted piperidines

Copper(II) chlorobenzoates react with substituted piperidines in an organic medium to give solid complexes having general formula [Cu(OOCR)2(L)] (R = 2-,3- or 4-ClC6H4 and L = 1-methyl, 1-ethyl and 2,6-dimethylpiperidine). All the complexes with copper(II) chlorobenzoates are of 1:1 stoichiometry irrespective of the amount of the ligand added and have been shown by physico-chemical methods to be binuclear, containing bidentate bridging carboxylate group except [Cu(OOCC6H4Cl-4) 2(2,6-Me2Pipd)] for which polymeric square pyramidal structure has been proposed. All the complexes show antiferromagnetic behaviour with the exception of [Cu(OOCC6H4Cl-4)2(2,6- Me2Pipd)] which is paramagnetic. The spin exchange parameter, -2J, for two of the complexes has been evaluated from magnetic susceptibility measurements at different temperatures, which corresponds to axial binuclear copper(II) complexes with S = 1.
