Abstract: The crystal structure determination of the title complex, bis[-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.
