Crystal Structure of 1-(4-Bromophenyl)-3-(4-nitrophenyl)triazene

摘要: The crystal structure of the title compound, C12H9BrN4O2, shows that stereochemistry about N=N double bond in diazoamine moiety is trans. dihedral angle [6.7(6)°] between terminal phenyl rings indicates whole molecule almost planar (r.m.s. deviation = 0.0945 A). Intermolecular N-H…O and C-H…O hydrogen bonds generate infinite one-dimensional linear chains along [0 0 1] direction. unequal distribution double-bond character among N atoms a delocalization π electrons over N=N-N(H) towards aryl substituents.
