Abstract
The crystal structure of the title compound, C15H14N4O3, reveals the expected trans stereochemistry about the N=N double bond in the diazoamine moiety. The interplanar angle [36.68(6)°] between the terminal phenyl rings indicates that the whole molecule deviates significantly from planarity (r.m.s. deviation = 0.3148 Å). Intermolecular O-H…O classical hydrogen bonds, and hydrogen bonds with a bifurcated geometry generate a three-dimensional molecule arrangement. The distribution of the double-bond character among the N atoms of the diazoamine moiety is unequal, indicating a delocalization of the π electrons over the N=N-N(H) group toward the terminal 4-carboxyphenyl substituent.
