Figure 7
Potential energy curves for TTF–TTF stacking for model systems Y, 2X and 1X (Fig. 4[link]) calculated at B2PLYP-D3BJ/6-311++G** level. The curves were obtained by changing the normal distances (R) for a series of offsets (r) and present the energies of the strongest interaction for each offset.
