The title compound, synthesized from 4,5-ethylenediseleno-1,3-diselenol-2-one (5,6-dihydro-1,3,4,7-tetraselenainden-2-one)via trimethyl phosphite coupling, has been characterized and several charge-transfer salts of this new π-donor have been prepared.
of an organic conductor incorporating localized magnetic moments, κ-(BETS)2FeCl4, were investigated down to 60–70 mK. Similar to the Br analogue, κ-(BETS)2FeBr4, κ-(BETS)2FeCl4 exhibited successive antiferromagnetic and superconductingtransitions with lowering temperature (TN=0.45 K, TC=0.1 K). That is, κ-(BETS)2FeCl4 is the second antiferromagneticorganicmetal that exhibits a superconducting transition

The crystal structure of (BEDSe-TSeF)2AuBr2 is very similar to that of the superconducting β-type BEDT-TTF system. Unlike the β-type salt with 2-dimensional(2D) closed Fermi surface, however, (BEDSe-TSeF)2AuBr2 has a 1D plane-like Fermi surface, as a result of strong dimerization and weak transverse interaction.
