A twisted ligand, 4,4'-dithiobis(pyridine), 4pds, was reacted with copper(II) carboxylates to synthesize one-dimensional coordination polymers: [Cu-4(CH3COO)(6)(mu(3)-OH)(2)(4pds)(2)](n) (1), [Cu(CH3COO)(2)(4pds)center dot 6H(2)O](n), (2), [{Cu-2(C6H5COO)(4)}(2)(4pds)(2)](n) (3), and [{Cu-2[CH3(CH2)(4)COO](4)}(2)(4pds)(2)](n) (4). The crystal structure of 1 reveals a repeated rhomboid structure in which the Cu-4(CH3COO)(6)(OH)(2) core is linked by two 4pds ligands. The 4:2 (Cu:4pds) stoichiometry of 1 transforms into the 1: 1 (Cu:4pds) one of 2 in aqueous solution. Compound 2 has a porous honeycomb-like structure, which is occupied by carboxylate ions and water Molecules. Compounds 3 and 4 are zigzag chains consisting of alternate linking of the Cu-2(RCOO)(4) unit and 4pds ligand. The variable-temperature magnetic susceptibility data of 1 and 3 are consistent with the net anti ferromagnetic interaction within the tetranuclear or dinuclear core.
