New organic metal (ET)4 (Hg2Cl6·C6H5Cl): Synthesis, structure, properties

Damping of field-induced chemical potential oscillations in ideal two-band compensated metals

“…The reduced field b = eBA 0 /h is in units of the characteristic field B = h/eA 0 , the effective masses are in units of the electron mass m e , the energies are in units of Ẽ = 2π 2 /m e A 0 and the temperature t in units of T = Ẽ/k B . Given a unit cell area A 0 =197.6 Å2 , which stands for (BEDT-TTF) 8 Hg 4 Cl 12 (C 6 H 5 Cl) 2 20 , we obtain B = 2093 T and T = 2812 K. Therefore, realistic experimental conditions yield small values of b and t compared to B and T , respectively. The semi-classical quantization of the energy levels in the presence of a magnetic field leads to the Landau equations:…”

Molecular quantum materials: electronic phases and charge dynamics in two-dimensional organic solids

“…Due to the lack of appreciable charge disproportionation in most of the commonly studied Mott insulators and quantum spin liquid compounds, a family of dimerized BEDT-TTF compounds has drawn particular attention, the κ-(BEDT-TTF) 2 Hg(SCN) 2 X series, where X = Cl − , Br − , I − , that was introduced almost twenty years ago by Lyubovskaya et al [77,[281][282][283][284]. In contrast to the κ-salts containing Cu-ion in the polymeric anion sheet, the BEDT-TTF molecules of the Hg-compounds are slightly displaced with respect to each other within a dimer, as shown in Figure 7(a).…”

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

“…In addition, the fairly narrow bandwidth and strong electron correlation of the ET complexes have afforded a variety of functional materials: namely, 2D superconductors ( 424 and Hg 2 Cl 6 (chlorobenzene) (4:1) 425 ). In summary, the characteristic features of the ET molecule and complexes are the following: 1) Non-planar neutral ET molecules become almost flat except the terminal ethylene groups in the ionic and partial CT complexes.…”
