Abstract: Copper(Ⅱ)-ferron(7-iodo-8-hydroxyquinoline-5-sulfonate) one-dimensional coordination polymer Na2n[Cu(Ferron)2]n ·6 n H2O was synthesized and investigated by X-ray diffraction method. The polymer exhibits a linear structure by the bis-iodine-axial coordination to the octahedral Cu(Ⅱ) center,which is stabilized by the iodine-aromatic ring(edge and face) and iodine-iodine interactions between the polymer lines,forming a special layer structure. The complex belongs to a triclinic system,space group P 1, a=0.648 4(19) nm, b=0.654 5(19) nm, c=1.911(6) nm, α=85.42(5)°,β=85.78(5)°,γ=72.99(4)°,V=0.772(4) nm3 and Z=1 .
