Two coordination polymers, [Cu(bpp)(H2O)(2)(ClO4)(2)](n) (1) and {[Cu(bpds)(2)(ClO4)(2)] center dot 1.5(H2O)}(n) (2) [bpp, 1,3-bis(4-pyridyl)propane and bpds, 4,4'-bipyridyl disulfide] have been synthesized and characterized by X-ray single crystal diffraction study and magnetic measurement. Both the coordination polymers display 1D chains with perchlorate anions acting as pendant ligands. In 1 undulated polymers are built by Cu(H2O)(2)(ClO4)(2) units connected by single bpp and in complex 2 Cu(ClO4)(2) fragments are linked by pairs of bpds ligands to form a double-stranded chain. The crystal packing evidences polymers of 1 involved in weak H-bonding interactions leading to a 3D supramolecular network. Magnetic study reveals weak antiferromagnetic interactions in both complexes.
