Structural and electrical properties of (BEDT-TTF)2X(diiodoacetylene) (X=Cl, Br): the novel self-assembly of neutral Lewis-acidic molecules and halide anions in a molecular metal
Abstract
A neutral Lewis-acidic molecule, diiodoacetylene, forms one-dimensional chains with halide anions (Cl– and Br–) and affects the donor (BEDT-TTF) arrangement in the cation radical salts, which exhibit metallic resistivity behaviour down to 1.6 K.
