Complex [Cu(2,2′‐bipy)(H 2 L 1 )] (ClO 4 ) 2 (1) has been synthesized by the self‐assembly of Cu(ClO 4 ) 2 with a rigid ligand 2,2′‐bipyridine and a flexible potential tetradentate ligand N, N '‐bis(hydroxyethyl)ethylenediamine (H 2 L 1 ). Crystal analyses reveal that the potentially tetradentate ligand H 2 L 1 acts in a tridentate mode by the coordination of one hydroxyl oxygen atom and two amino nitrogen atoms. The Cu(II) atom coordinates additionally with two bipyridyl nitrogen atoms, giving a distorted square pyramidal geometry. Each complex molecule is connected with four surrounding molecules along the ac plane by multiple hydrogen bonds, leading to 2D sheets constituted with 0.7874 nm × 1.0891 nm metallomacrocyclic rectangles. Each vertex of the rectangle is occupied by a copper atom, and the four sides are comprised of multiple hydrogen bonds.
