, p. 993 - 996 (1984)
In the crystal of (BMDT-TTf)3PF6(1,2-dichloroethane) (BMDT-TTF=bis(methylenedithio)-tetrathiafulvalene), there are two crystallographically independent BMDT-TTf molecules whose molecular planes are approximately perpendicular to each other.This new type of molecular arrangement achieves the two-dimensional S...S network.

Reaction of methylenedithio-1,3-dithiol-2-one with sodium methanolate resulted in the anionic ligand mdt2- (mdt = 1,3-dithiole-4,5-dithiolate) which has been co-ordinated to nickel. The salt [NBu4][Ni(mdt)2] was successfully crystallised and its crystal structure showed that the Ni(mdt)2 unit is significantly distorted from planarity. Electrochemical studies showed that [NBu4][Ni(mdt)2] can be further oxidised in two steps via the neutral [Ni(mdt)2] complex to a partially oxidised positively charged complex. The neutral complex has also been successfully synthesized by oxidation with TCNQ. The redox potential of the oxidation from the neutral to the partially oxidised positive Ni(mdt)2 complex is relatively low, +0.60 V, making this compound a promising precursor for the preparation of conducting materials, based on derived cation radical salts.

Syntheses of the bis(heterocycle)-fused bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives 7 and 8, the heterocycle-fused BEDT-TTF, methylenedithio(ethylenedithio)tetrathiafulvalene (MET), and ethylenedithiotetrathiafulvalene derivatives 9-11, and the 1,3-dioxolane derivative of MET 12a and its analogues 12b-d are described. The heterocycle-fused ketones 17 and 19 with cis ring fusions could be prepared by the BF3-promoted reaction of tin dithiolate 13 with dihaloheterocycles 15 and 16 in good yields, respectively, and served as key intermediates for the (RO)3P- and/or Me3Al-promoted coupling syntheses of these new tetrathiafulvalene donors 7-12. Further, the electrochemical properties of new donors 8-12 by the use of cyclic voltammetry and the molecular structures of 9a, 10a, 11, and 12a by X-ray crystallographic analyses are also reported.

, p. 1635 - 1640 (2007/10/03)
With the goal of obtaining new ethylenedithiolate transition metals complexes, unstable tetrabutylammonium bis(1,3-dithiol-4,5-dithiolato)niccolate(III) and stable tetrabutylammonium bis(5,6-dihydro-1,4-diselenin-2,3-dithiolato)niccolate(III) were synthesized. The two complexes were characterized by elemental analysis and IR and electron absorption spectroscopy, and the second, also by voltammetry. A new convenient procedure was proposed for preparation of 1,3-dithiol-2-thione which is a key initial compound in the synthesis of the title complexes.
