A trinuclear copper complex, [Cu₃L₂](ClO₄)₂, where H₂L is 1,3-bis(2-hydroxy­benzoyl­imino)­propane

The crystal structure determination of the title complex, bis­[μ-1,3-bis(2-oxy­benzoyl­imino)­propane]­tricopper(II) ­diper­­chlor­­ate, [Cu₃(C₁₇N₂H₁₆O₂)₂](ClO₄)₂, shows that a Cu^II atom, located on a crystallographic inversion centre, is coordinated by four bridging O atoms of two L ligands [H₂L is 1,3-bis(2-hydroxy­benzoyl­imino)­propane] and two perchlorate O atoms, in elongated octahedral geometry. The other two Cu^II atoms are in a distorted square-pyramidal geometry, ligated by N and O atoms of the L ligand and an O atom of a perchlorate ion. In the complex, the Cu—N bond length is 1.948 (4) Å and the Cu—O bond lengths are in the range 1.930 (3)–1.984 (3) Å.
