A series of crown ether substituted vinylogous tetrathiafulvalenes (TTFVs) is synthesized via oxidative coupling of bisdithiafulvenes. The rigidification of the crown ether ring after complexation has appeared as a decrease of the apparent electron-transfer kinetics and has little effect on the thermodynamics as the crown ether is far from the redox center.

The synthesis and the chelating ability of the tetrathiafulvenyl-acerylacetonate anion are investigated in regard to metal M(super H) cation (M(super h) = Ni, Zn) giving rise to the first metal complexes involving such rodox-active ligands. Electrochemical investigation, associated with the structural analysis of these complexes, evidence intramolecular interactions between two tetrathiafulvalene (TTF) cores of a complex.

Research describes the synthesis of porphyrazinediols, their conversion into solitaire complexes, and chemical oxidation of the polydentate noninnocent macrocycles. Results demonstrate that porphyrazinediols are a novel class of redox-active ligands whose diol chelating group is directly attached at the beta-positions of the macrocycle.

The chemoselective reduction of vinylmercury chlorides with tributylstannane and a radical inhibitor produced several vinylmercury hydrides. The vinylmercury hydrides are composed of a mercury unit with a bonding angle of 180 degrees. The HgH bond of the methylmercury hydride has the lowest harmonic frequency among the vinylmercury hydrides. Diethenylmercury has the largest Hg-C bond shortening compared to the monosubstituted compounds.

A single component molecular conductor is isolated from electrocrystallization of the monoanionic gold bis(dithiolene) complex based on the N-ethyl-1,3-thiazoline-2-thione-4,5-dithiolate (Et-thiazdt) ligand. First-principles density functional theory (DFT) calculations have shown that the ground state is antiferromagnetic with a very small band gap.
