Ethyl (E)-2-methoxyimino-2-(4-nitro-benzoyl)acetate

Abstract

The title molecule, C12H12N2O6, features an E conformation about the oxime group. The methoxy-imino and ester residues are effectively coplanar with each other (r.m.s. deviation for the nine non-H atoms = 0.127 Å) and almost orthogonal [with dihedral angles of 99.44 (13) and -77.85 (13)°, respectively] to the carbonyl and nitro-phenyl groups which lie to either side of this central plane. The crystal structure is consolidated by C - H⋯O contacts.
