摘要
In the title compound, C(7)H(7)BrN(2)O, both the urea moiety [maximum deviation 0.003 (2) angstrom] and the benzene ring are essentially planar [maximum deviation 0.003 (2) angstrom] but are rotated with respect to each other by a dihedral angle of 47.8 (1)degrees. The crystal assembly is stabilized by N-H center dot center dot center dot O hydrogen bonds between all NH protons as conventional hydrogen bond donors and the C=O oxygen as a trifurcated hydrogen-bond acceptor. Both the overall molecular geometry and the crystal packing of the title compound are very similar to those of N-phenylurea, which is underscored by a practically isostructural relationship between these two urea derivatives.
