Abstract
The crystal structure of the title compound, C14H9F6N3, shows the expected stereochemistry trans about the N=N double bond in the diazoamine moiety. The interplanar angle [8.3(1)°] between the terminal phenyl rings indicates that the whole molecule is almost planar (r.m.s. deviation = 0.0929 Å). The molecule shows intramolecular N-H…(F1, F2) bifurcated, and non-classical C-H…F hydrogen bonds. The unequal distribution of the double-bond character among the N atoms of the diazoamine group indicates a delocalization of the π electrons over the N=N-N(H) moiety towards the terminal 2-trifluoromethylphenyl substituents.
