Two new silver(I) - dithioether coordination polymers based on the combination of the dithioether ligand L = CH3-S(CH2)(3)S-CH3 and AgX silver salts, where X = NO3- (1) and CF3CF2COO- (2), have been synthesized and characterized. In both coordination polymers, the dithioether building blocks propagated the silver (I) centers to build chains, in which the counteranions complete the coordination sphere of the metal centers. Furthermore, the tubular chains in 2 are, in turn, associated through weak C-F center dot center dot center dot F-C interactions into 3D-structures. The thermogravimetric investigation reveals that those complexes decompose in a single step respectively to metallic silver. The stoichiometries of the obtained polymers were found to be dependent of the starting metal-to-ligand ratio, (C) 2011 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
