A New Mercury-based Cation Radical Salt: α-(BEDT-TTF)<sub>2</sub>Hg(SeCN)<sub>2</sub>Cl

ORAL

Abstract

BEDT-TTF [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene, henceforth referred to as ET] cation radical salts continue to serve as important physical representations of various theoretical quantum systems. The arrangement of ET radical cations in these materials have dramatic effects on their physical properties. Here we report the synthesis of the new α-(ET)2Hg(SeCN)2Cl salt. Single crystals, crystallizing in the monoclinic space group P21/n, were prepared through the use of electrocrystallization.1 The two dimensional crystal structure is characterized by layers of ET radical cations separated by dimerized Hg(SeCN)2Cl- anions. The synthesis, structure, and magnetization, heat capacity, electron-spin-resonance, and Raman measurements are reported.
