Abstract

The synthesis, crystal structure, conductivity and electronic band structure of the new molecular metal α-(BEDT-TTF)₂TlHg(Se_1-xS_xCN)₄ (x = 0.125) are reported. α-(BEDT-TTF)₂TlHg(Se_1-xS_xCN)₄ (x = 0.125) is isostructural with all other members of the family of α-(BEDT-TTF)₂MHg(XCN)₄ salts and is a stable metal down to very low temperatures. A general study of the electronic structure of all structurally characterized α-(BEDT-TTF)₂M Hg(XCN)₄ salts as well as α-(BEDT-TTF)₂I₃, α-(BEDT-TTF)₂IBr2 and Q-(BEDT-TTF)₄PtBr₆ is also reported. Different aspects related to the electronic structure of these salts like the stability of the metallic state and the nature of the Fermi surface are discussed and correlated with the details of their crystal structures. The origin of the different dimensionality of the carriers for the α-(BEDT-TTF)₂MHg(XCN)₄ salts (i.e., 1D electrons but 2D holes) , the metal to insulator transition in α-(BEDT-TTF)₂I₃ and the semiconducting behavior of α-(BEDT-TTF)₂IBr₂ and α-(BEDT-TTF)₄PtBr₆ are also discussed.
