“…The structural features of 3 are similar to those reported for pbromophenyldiphenyl)methyldifluoramine. 10 The C-N distance of 1.523(2) Å found in 3 is longer than the corresponding distance of 1.481 Å in triphenylmethylamine. 11 The presence of two highly electronegative fluorines on the nitrogen atom reduces back-donation from the nitrogen lone pair, thereby decreasing the C-N bond order.…”

The crystal and molecular structure of (N,N-difluoroamino)-2,4-dinitrobenzene has been determined from three-dimensional X-ray data collected by counter methods. The compound crystallizes in the monoclinic space group P21/c with eight molecules in the unit cell. Cell dimensions are a = 11.974 (4), b= 11-040 (4), c= 14.435 (6) ~, fl= 119.76 (5) , V= 1657 &3. Refinement for 1658 reflexions with FZo> 2a(Fo) z converged to conventional and weighted R values of 0.058 and 0.042. The nitrogen atom of the amine group has a pseudo-tetrahedral coordination and evidence for a nonbonded interaction between this atom and an oxygen atom of the ortho nitro group is given. The details of the geometry of the molecule are compared with those previously determined. The molecular packing is also discussed.
