TNAP

If we now incorporate functional groups in the CeHe-based molecules we will have important molecules such as CA, DMe-DCNQI, TCNQ, TMPD, TNAP and ITT, but the really big jump is encountered when pentagons are allowed to be included. The possibilities to build new molecules become even more numerous than with only CeHe pieces, although we already had an immense number...

The structure of TTF/TNAP like that of TTF/TCNQ is composed of stacks of TTF and TNAP ions arranged in alternating layers with similar interionic distances in the two compounds (cation cation = 0.34 nm anion anion = 0.31 nm) (see Fig. 26). Flowever, the structure within the layers is quite different with the TTF ions in the TNAP salt all tilted in the same direction whereas in TTF/TCNQ the TTF ions in adjacent columns are inclined in...
