The trinuclear copper(II) complex [(LCu)2Cu(H2O)](ClO4)2·2H2O (L = 4,7-bis(2-hydroxybenzyl)-1-oxa-4,7-diazacyclononane) has been synthesized and its crystal structure has been determined. From temperature dependent magnetic susceptibility measurements strong intramolecular antiferromagnetic coupling of the spins has been detected yielding an S = 1/2 ground state. The trinuclear species dimerizes in acetone solution to yield {[(CuL)2Cu]2}(ClO4)4 which has an S = O ground state.
