Dichlorido-1κCl,3κCl-bis{μ-2,2′-[propane1,3-diylbis(iminomethylene)]diphenolato}1:2κ6O,N,N′,O′:2:3κ6O,O′:N,N′,O′-tricopper(II)

The title linear trinuclear copper(II) complex, [Cu-3(C17H20N2O2) Cl-2(2)], 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 ((1) over bar). 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.
