A novel conducting charge-transfer salt: (BEDT-TTF)₃Cl₂·2H₂O

Structure of the organic conductor (BEDT-TTF)2Br.C2H4(OH)2

“…In spite of this, this scheme of hydrogen-bond formation in (BEDT- TTF)2Br.C2H4(OH)2 may also be possible, since it involves all the Br anions, just like the salts (BEDT-TTF)aBrE(H20)2 (Urayama et al, 1987) and (BEDT-TTF)3C12. (H20)2 (Moil & Inokuchi, 1987a,b;Rosseinsky et al, 1988). Unfortunately, determination of O-atom positions is not sufficiently accurate to allow us to draw definite conclusions about the system of anion hydrogen bonds in the crystal.…”

“…(H20)2 (Urayama, Saito, Kawamoto & Tanaka, 1987), (BEDT-TTF)3C1E. (H20)2 (Moil & Inokuchi, 1987a,b;Rosseinsky, Kurmoo, Talham, Day, Chasseau & Watkin, 1988) and /3-(BEDT-TTF)3Br2 (Parkin, Engler, Lee & Schumaker, 1985) testify to the fact that these compounds have a C:A ratio of 3:2 and a metal-insulator transition temperature (TMI) of 100-185K. An exception is the salt (BEDT-TTF)3C1E.…”

(BEDT-TTF)3[CuBr4]

“…Mori's sample was electrocrystallized by oxidation of both BEDT-TTF and CuIBrf in a chlorine-containing solvent, so it is probable that his crystal contained some C1 (Rosseinsky et al, 1988), thus reducing the observed electron density at the Br sites. Our crystals were prepared in a non-chlorinated solvent.…”

Superconductivity, incoherence and Anderson localization in the crystalline organic conductor (BEDT-TTF)3Cl2$middot$ 2H2O at high pressures

“…• [11]. The conducting planes of the (BEDT-TTF) molecules lie in the ab-plane with the long axis of the molecules lying approximately parallel to the c-axis (see Figure 2).…”

“…It consists of three independent (BEDT-TTF) molecules, two chlorine atoms and two water molecules. Six (BEDT-TTF) molecules collectively donate four electrons to each anion leaving each molecule with an average charge of + 2 3 e (from [11]). Right: The Fermi surface of Whangbo et al [6]; (a) shows the Q2D closed electron pocket, (b) the Q1D electron sheet and (c) the Q1D hole sheet.…”
