title: N,N'-Bis(2,2,3,3,4,4,4-hepta-fluoro-butyl)naphthalene-1,4:5,8-tetra-carboximide.
abstract: The title mol-ecule, C(22)H(8)F(14)N(2)O(4), lies across a crystallographic inversion center with the naphthalene diimide core essentially planar (mean deviation from plane is 0.0583 Å). The CF(2) groups in the perfluorobutyl chains are in an energetically favorable all trans conformation. In the crystal structure, mol-ecules are packed in slightly displaced layers so that the side chains overlap the aromatic naphthalene diimide rings, thus minimizing any possible π-π overlap.
