Abstract
A three dimensional volume packing analysis of the crystal structures of quasi-one-dimensional ion-radical solids of the type (D)2 ∔ X− is presented. It is found that the (TMTSF)2 ∔ X−(X ≠ NO3) solids are loosely packed when compared with solids where D is an aromatic hydrocarbon. It is suggested that (TMTSF)2 ∔ X−(X ≠ NO3) are formed under conditions of kinetic control. A direct, broadly applicable approach to the synthesis of aromatic molecular (e.g. tetratellurotetracene (TTeT) and bis-(2-naphthyl)ditelluride) and supramolecular (e.g. poly-p-phenylene selenide (PPSe) and -telluride) materials is outlined. Our initial studies (powder data) of the structural and room temperature electrical properties of solids derived from TTeT and PPSe by electron transfer are summarized. The crystal and molecular structures of two forms of bis-(2-naphthyl) ditelluride have been determined using single crystal methods, and conformational polymorphism was observed.
