The title linear trinuclear copper(II) complex, [Cu(3)(C(17)H(20)N(2)O(2))(2)Cl(2)], was obtained from N,N'-bis-(2-hydroxy-benz-yl)-1,3-propane-diamine and CuCl(2). The overall charge of the three Cu(2+) ions is balanced by four deprotonated phenol groups and two Cl(-) ligands. The complex is centrosymmetric with the central Cu(2+) occupying a special position (). This Cu(2+) ion is coordinated by the four phenolate O atoms in a square-planar fashion. The second Cu(2+) occupies a general position in a square-pyramidal fashion. Two phenolate O atoms and two amine N form the basal plane, with Cl(-) ligands occupying the fifth coordination site.
