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.

Paragraph 0032; 0035-0037, (2017/04/03)
The invention discloses an organic-inorganic hybridization molecular magnet with room-temperature metallicity and a preparation method of the molecular magnet. The molecular formula of the molecular magnet with the room-temperature metallicity is BETS3[Cu2(C2O4)3]B2, wherein BETS represents disulfo-diethylene tetraselenafulvalene; and B represents an alcohol compound. The preparation method of the molecular magnet with the metallicity comprises the step of performing electrochemical reaction on an ammonium salt of cupric oxalate with BETS in an electrochemical tank by taking the alcohol compound as an electrolyte solution so as to obtain the molecular magnet with the room-temperature metallicity on an anode. According to the preparation method of the molecular magnet with the room-temperature metallicity, single crystal of the molecular magnet with room-temperature metallicity is prepared in an organic solvent system from an organic pi electron system and Jahn-Teller distorted magnetic anion. The molecular magnet with room-temperature metallicity, which is provided by the invention, is good in crystal quality, single in product and high in yield.
