## Abstract Two new bis(N,O‐bidentate) Schiff base ligands with asymmetric spacers between the donor sites have been synthesized. The asymmetric ligand H~2~L^1^ self‐assembles with copper(II) ions to give rise to a dinuclear copper(II) complex [Cu~2~L^1^~2~] (1), while a more flexible ligand H~2~L^
