چکیده

A dual-functional organic-inorganic hybrid (BEDT-TTF)2Cu2(HCOO)5 (1) (BEDT-TTF=bis(ethylenedithio)tetrathiafulvalene) was obtained through the electrochemical oxidation of neutral BEDT-TTF in the presence of an ammonium salt of the one-dimensional copper-formate framework [(C2H5)3NH]2Cu2(HCOO)5 in a C6H5Cl-C2H5OH solution. Compound 1 was composed of organic donor BEDT-TTF+0⋅5 in a θ-phase arrangement and Jahn-Teller distorted (4,4) grid anion sheets [Cu2(HCOO)5-] n with S=1/2. We identified the material as a semiconductor with values of σ300K=10-1 S cm-1. The anion sheet is a coordination isomer of [Cu2(HCOO)5-] n and, compared with the starting material, shows antiferromagnetic behavior as the well-known inorganic Cu-O, Co-O square layers for creating inorganic conducting magnets. Long-range antiferromagnetic ordering was observed at 8.0 K.

Structural diversity and physical properties of paramagnetic molecular conductors based on bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) and the tris(chloranilato)ferrate(III) complex.

Electrocrystallization of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) in the presence of the tris(chloranilato)ferrate(III) [Fe(Cl2An)3](3-) paramagnetic chiral anion in different stoichiometric ratios and solvent mixtures afforded three different hybrid systems formulated as [BEDT-TTF]3[Fe(Cl2An)3]·3CH2Cl2·H2O (1), δ-[BEDT-TTF]5[Fe(Cl2An)3]·4H2O (2), and α‴-[BEDT-TTF]18[Fe(Cl2An)3]3·3CH2C...

Quantum criticality in an organic spin-liquid insulator κ-(BEDT-TTF)2Cu2(CN)3

A quantum spin-liquid state, an exotic state of matter, appears when strong quantum fluctuations enhanced by competing exchange interactions suppress a magnetically ordered state. Generally, when an ordered state is continuously suppressed to 0 K by an external parameter, a quantum phase transition occurs. It exhibits critical scaling behaviour, characterized only by a few basic properties such...

A Novel BEDT-TTF-based Purely Organic Magnetic Conductor, α-(BEDT-TTF)2(TEMPO-N(CH3)COCH2SO3)·3H2O

A new BEDT-TTF-based salt with an organic free radical TEMPO has been prepared. The salt consists of alternate layers of conducting and magnetic sheets, between which are short S(BEDT-TTF)...O(TEMPO) contacts. The magnetic susceptibility is well modelled by the combination of a Curie-Weiss and a 2-D Heisenberg models with J = -89 K and θ = +0.05 K.

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

The conducting properties of the pressure-induced, layered organic superconductor (BEDT-TTF)3Cl2·2H2O have been studied at 13.5 and 14.0 kbar using low temperatures, high magnetic fields and two-axis rotation. An upper critical field that is significantly larger than that expected from the Pauli paramagnetic limit is observed when the field is applied parallel to the conducting layers. The angl...
