Abstract: Complex [Cu(2,2'-bipy) (H2L1)] (ClO4)(2) (1) has been synthesized by the self-assembly of Cu(ClO4)(2) with a rigid ligand 2,2'-bipyridine and a flexible potential tetradentate ligand N, N'-bis(hydroxyethyl)ethylenediamine (H2L1). Crystal analyses reveal that the potentially tetradentate ligand H2L1 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 mn x 1.0891 nm metallomacrocyclic rectangles. Each vertex of the rectangle is occupied by a cop. per atom, and the four sides are comprised of multiple hydrogen bonds.
