Abstract: The title molecule, C₂₂H₈F₁₄N₂O₄, lies across a crystallographic inversion center with the naphthalene diimide core essentially planar (mean deviation from plane is 0.0583 Å). The CF₂ groups in the perfluorobutyl chains are in an energetically favorable all trans conformation. In the crystal structure, molecules are packed in slightly displaced layers so that the side chains overlap the aromatic naphthalene diimide rings, thus minimizing any possible - overlap.
