Abstract: One-dimensional cyanide-bridged bimetallic coordination polymer [CuL(H2O)2]n[(CuL)·(μ-CN)2Fe(CN)4]2n·(H2O)2nwas synthesized and structurally characterized. The coordination polymer crystallizes in a monoclinic system of the space group C2/c with a=2.9831(5) nm, b=1.5274(3) nm, c= 1.7253(4) nm, β=107.68(2)°, V=7.490(3) nm3, Z=8, Dc=1.382 g/cm3, F(000)=3260, R=0.0593, wR2=0.1323, S=0.885. The one-dimensional zigzag chain extents through Cu-CN-Fe-CN-Cu linkages. The adjacent two polymer chains are linked by the O-H……NChydrogen bonding between [CuL(H2O)2]2+and [Fe(CN)6]3-ions to form hydrophilic channels in which water molecules are included.

Key words: Coordination polymer of copper(Ⅱ) macrocyclic complex, Ferricyanide, One-dimensional zigzag chain, Hydrophilic channels
