摘要
The asymmetric unit of title compound, C12H12N2O4, consists of two independent molecules. In each molecule, the oxadiazine ring has a flattened envelope conformation with the methylene C atom as the flap atom, and the ethoxycarbonyl unit is in a syn-periplanar conformation with respect to the oxadiazine ring as indicated by O-C-C=O torsion angles of 1.9 (4) and 2.5 (4)degrees. The dihedral angles between the mean plane of the oxadiazine ring and the phenyl ring are 80.07 (13) and 42.98 (14)degrees. In the crystal, molecules are linked by C-H center dot center dot center dot O hydrogen bonds and stacked in a double-column along the a-axis direction.
