Crystal structures, and electrical conduction and magnetic properties in CuCl4 salts of dimethylthio- and ethylenedithio-tetrathiafulvalenothioquinone-1,3-dithiolemethides

“….379 emu K f.u. 21 (f.u.~(1) 2 ?CuCl 4 ) and h~20.1 K. On the other hand, for (2) 3 ?CuCl 4 a gradual decrease in x p T was observed on cooling from 300 to ca. 170 K. Between ca.…”

“…The C, h and x p values which best reproduced the experimental data were 0.388 emu K f.u. 21 (f.u.~(2) 3 ?CuCl 4 ), z3.1 K and 4.5610 24 emu f.u. 21 , respectively.…”

Development of Conductive Organic Molecular Assemblies: Organic Metals, Superconductors, and Exotic Functional Materials

“…In 1998-1999, Ueda et al reported the highly conductive semiconductors 33b, 33d, 33e, and 33f. 128,129 Especially single crystals of 33d (M = Ni, X = Se, R = Et) showed a high conductivity of ' RT ¼ 2:8 S cm À1 with a very small gap of " g ¼ 0:028 eV, 128 and 33e (M = Cu, X = S, 2R = -CH 2 CH 2 -) was more conductive even in the pellet sample (' RT ¼ 3:7 S cm À1 ). 129 The magnetic susceptibility of 33e after subtracting the Curie term (Curie constant: 1:2 Â 10 À2 emu K mol À1 ) is temperature independent as expected from Pauli paramagnetism (3:6 Â 10 À4 emu mol À1 ).…”

Hydrogen bond-promoted metallic state in a purely organic single-component conductor under pressure

“…In this material, conductive p electrons delocalize over the tetrathiafulvalene (TTF)-type large ligand skeleton, and as a result, the HOMO-LUMO gap is made smaller 1 . Subsequently, such single-component molecular conductors composed of metal complexes have been intensively developed [2][3][4][5][6][7] . On the other hand, the former idea (i) has given rise to the first purely organic conductor, the perylene-bromine complex 8 , followed by an enormous number of charge-transfer complexes, such as TTF-TCNQ (tetrathiafulvalene-tetracyanoquinodimethane) and BEDT-TTF (bis(ethylenedithio)tetrathiafulvalene) complexes [9][10][11][12][13][14][15][16][17] .…”
