Quasi Three-Dimensional Electrical Conductor Having Alternating Mixed Stacks: Tetrakis(methyltelluro)tetrathiafulvalene (TTeC1-TTF)·TCNQ Complex

Tetrakis(methyltelluro)tetrathiafulvalene (TTeC1-TTF) and TCNQ give a 1:1 CT complex with alternating mixed stacks whose electrical conductivity along the stacking direction is 1.0×10−2 S cm−1. Quasi three-dimensional electrical conductivity was observed owing to its unique crystal structure where exist the two equivalent neighboring stacks linking each other with short Te···N contacts. These properties are compared with those of TTC1- and newly prepared TSeC1-TTF·TCNQ complexes.
