Novel tetranuclear copper vertical bar 2 + 4 vertical bar cubanes 1 and 2 have been synthesized from the reaction of hydrated copper salts/precursors with N,O chelating beta-ketoaminato ligands. Creation of 1 and 2 occurs by in situ generation of the tridentate chelating species HL1O(2-) via copper mediated C-O bond formation and dearomatization of H(3)L1, while anhydrous salts afforded mononuclear complex 3.
