P. Cassoux et al., New salts derived from BETS and M(dmit)(2) molecules with magnetic or long-lived excited states counter-ions, SYNTH METAL, 120(1-3), 2001, pp. 1085-1086
Four crystal phases are obtained from BETS (BETS = bis(ethylenedithio)tetra
selenafulvalene) and the [Cu2Cl6](2-) anion. Their synthesis, structures, a
nd properties are presented. The synthesis, structure and properties of the
theta-(BETS)(4)[Fe(CN)(5)NO] phase, which involves an anion exhibiting lon
g-lived excited states, is reported. The structure and properties of M(dmit
)(2) salts with magnetic cations (metalloceniums, TEMPO) are mentioned.
