摘要

Complex [Cu(2,2'-bipy)(H2L1)] (C1O4)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 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.
