Pocinho, Alexandre; Mallet-Ladeira, Sonia; Hureau, Christelle; Gras, Emmanuel published the artcile< N,N′-Bis(4-bromophenyl)-N,N′-dimethylurea>, Quality Control of 639520-70-0, the main research area is bisbromophenyl dimethylurea preparation crystal structure.
The structure of the title compound, C15H14Br2N2O, at 180 K has monoclinic (P21/n) symmetry. It was obtained unexpectedly from the decomposition of the parent 4-bromo-N-tert-butoxycarbonyl-N-methyl-aniline. It exhibits an ′endo′ conformation with angles between the two aromatic rings slightly lower than the average values found for similar compounds on the Cambridge Structural Database. In the crystal, C-H···O hydrogen bonds and short Br···Br halogen bonds [3.444 (1) Å] are observed
