The oxidation of 2,3,6,7‐tetrakis(2‐cyanoethylthio)tetrathiafulvalene (TCE‐TTF) with hexafluoroacetylacetonate (hfac) salts of paramagnetic (Co II , Mn II ) and diamagnetic (Zn II , Cd II ) ions in the presence of tetrahedral anions (BF 4 – and ClO 4 – ) resulted in the isolation of four isostructural salts. The structure of these salts revealed an infinite two‐dimensional network due to the coordination of the nitrilo arms of TCE‐TTF to the metal. Short interplanar S ··· S interactions between two planes involving TCE‐TTF give a third dimension to this polymer. TTF ligands are fully oxidized, and hence these materials show semiconducting behaviour. Spectroscopic and magnetic studies of the paramagnetic‐transition‐metal‐containing polymers are also presented.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
