Bis-fused π-electron donors having alkylthio chains, CnTET-TTP (2-[4,5-bis(alkylthio)-1,3-dithiol-2-ylidene]-5-(4,5-ethylenedithio-1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene; n = 2–4) have been synthesized. C2TET-TTP (1a) forms radical-cation salts with BF4- and ClO4-, which are metallic (σrt = 900-2500 S cm-1) down to helium temperatures. The I3 salts of C3TET-TTP (1b) and C4TET-TTP (1c) are

oligo(phenyleneethynylene)s (OPEs) are linked together via one vinylogous linker. These molecules thus incorporate a central stilbene part from which the two OPE wires are propagating in a so-called "H-cruciform"-like motif. Each ring of the central stilbene unit also contains a redox-active dithiafulvene (DTF) unit and this part of the molecule can thus be considered as an extended tetrathiafulvalene (TTF)

radical cations and intermolecular complexes based on π-extended tetrathiafulvalenes (TTFs) is central for the development of organic conductors. On another front, redox-controlled dimerization of radical cations has recently been recognized as an important tool in supramolecular chemistry. Here we show that π-extended TTFs based on the indenofluorene core, prepared by Horner–Wadsworth–Emmons reactions

Four complexes with 4′,5′-diaza-9′-[4,5-bis(methylthio)-1,3-dithiol-2-ylidene]fluorene (L1) or 4′,5′-diaza-9′-[4,5-bis(ethylthio)-1,3-dithiol-2-ylidene]fluorene (L2) were synthesized. The complexes [Co(L1)2Cl2]·2CH3OH (1), [Cu(L2)2Cl2]·CH3OH·0.5CH2Cl2 (3), and [Cu(L2)2Br2]·CH3OH (4) adopt a trans configuration and the compound [Cd(L1)2(NO3)2] (2) is a cis structure. Short S···S, C···C, and C···S contacts

byproducts were identified as a novel type of compounds, namely bis(2-alkylthio-1,3-dithiol-1-ium-4,5-dithiolato)zinc compounds 3, being composed of two identical 2-alkylthio-1,3-dithiol-1-ium-4,5-dithiolate moieties coordinated to a single zinc(II) atom and were characterized by elemental analyses and different spectroscopic techniques as well as single-crystal X-ray structure analyses. A comparison
