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.
