The crystal structure determination of the title compound, C 14 H 14 N 2 O 3 , reinvestigated using low temperature X-ray diffraction data, confirms the earlier report. However, the almost planar molecule is observed in a disordered state. Two partial molecules exist in unequal proportions (75:25). They are related to one another through a pseudo-twofold axis of rotation contained in the molecular plane and normal to the molecular axis. The dihedral angle between the two aromatic systems is 22.1 (9)° |
