Synthesis and characterization of a polymeric copper (II) complex bridged with perchlorate ion: X-ray crystal structure of Cu(N,N′-bis(3-aminopropyl)ethylenediamine)(ClO4)2·H2O

The title complex was prepared by the reaction of N,N′-bis(3-aminopropyl)ethylenediamine (3,2,3-tet) and NaClO4 in the presence of copper(II) ion. The complex forms a coordination polymer bridged with μ-bidentate perchlorato ligand. The geometry around copper(II) ion is tetragonally distorted octahedron by the coordination of four nitrogens of 3,2,3-tet with square-planar arrangement and two perchlorato ligands in apical sites. An water molecule of the unit complex is located between [Cu(3,2,3-tet)]2+ and uncoordinated perchlorate with hydrogen bonds.
