Abstract: The structure of C₁₀H₁₀N₂·C₁₀F₈, (I), comprises mixed stacks of parallel (within 2°) neutral molecules, overlapping in a `graphitic' mode. Molecular geometry and UV-visible spectra indicate the absence of charge transfer. Structure (I) in space group P2₁ is close to P2₁/c and pseudo-isostructural with the 1:1 complex of naphthalene and C₁₀F₈, hence the crystal packing of (I) is governed largely by quadrupole-quadrupole interactions, hydrogen bonding of NH₂ groups (including a relatively strong N-HF bond of 2.16  Å) being less important.
