Dichlorido-1κCl,3κCl-bis{μ-2,2′-[propane-1,3-diylbis(iminomethylene)]diphenolato}-1:2κ6O,N,N′,O′:O,O′;2:3κ6O,O′:O,N,N′,O′-tricopper(II)

Abstract

The title linear trinuclear copper(II) complex, [Cu3(C17H20N2O2)2Cl2], was obtained from N,N′-bis(2-hydroxybenzyl)-1,3-propanediamine and CuCl2. The overall charge of the three Cu2+ ions is balanced by four deprotonated phenol groups and two Cl− ligands. The complex is centrosymmetric with the central Cu2+ occupying a special position (overline{1}). This Cu2+ ion is coordinated by the four phenolate O atoms in a square-planar fashion. The second Cu2+ 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.
