N,N,N,N-Tetra-kis(2,3,4,5,6-penta-fluoro-benzo-yl)pyridine-2,6-diamine.
The title compound, C(33)H(3)F(20)N(3)O(4), is a highly fluorinated organic imide that was isolated as an unexpected product from the reaction of 2,6-diamino-pyridine with 2,3,4,5,6-penta-fluoro-benzoyl chloride in a 1:2 molar ratio. The mol-ecule is located on a twofold axis and one of its symmetry-independent 2,3,4,5,6-penta-fluoro-benzoyl groups is disordered over two sets of sites, the occupancy of the major component being 0.773 (3). In the major component, the dihedral angle between the perfluoro-phenyl groups is 63.64 (10)°, and these groups form dihedral angles of 67.14 (7) and 21.1 (2)° with the pyridine core. Short inter-molecular C-H⋯O and C-H⋯N contacts are found in the crystal structure.
