N (2),N (2),N (6),N (6)-Tetra­kis(2,3,4,5,6-penta­fluoro­benzo­yl)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-diamino­pyridine with 2,3,4,5,6-penta­fluoro­benzoyl chloride in a 1:2 molar ratio. The mol­ecule is located on a twofold axis and one of its symmetry-independent 2,3,4,5,6-penta­fluoro­benzoyl 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 perfluoro­phenyl groups is 63.64 (10)°, and these groups form dihedral angles of 67.14 (7) and 21.1 (2)° with the pyridine core. Short inter­molecular C—H⋯O and C—H⋯N contacts are found in the crystal structure.
