The molecular structures and a comparison of the crystallographic packing in the TCNQ family for (a) TCNQ, (b) F2-TCNQ and (c) F4-TCNQ. The molecular packing viewed along different crystallographic directions for (d)/(g) TCNQ, (e)/(h) F2-TCNQ and (f)/(i) F4-TCNQ. Note that F2-TCNQ has the superior transporting nature [highlighted by a coloured crown in the background in part (b)] within the family. |
