The reaction between tetrathiafulvalene (TTF) e tetracyanoethylene (TCNE) yields two polymorphs with similar molecular structure. Both polymorphs display a stack structure of the type . . . (TTF-TTF)(TCNE-TCNE)(TTF-TTF)(TCNE-TCNE) . . . but they differ in crystal structure for hydrogen bonding system and lamellar sheets. These two CT complexes possess an high resistivity and a degree of charge- transfer of 0.54e estimated through the C-S bond length.

Abstract

These two CT complexes possess an high resistivity and a degree of charge- transfer of 0.54e estimated through the C-S bond length.File in questo prodotto:
