Methyl (2Z)-3-[(4-nitro­phen­yl)carbamo­yl]prop-2-enoate

By Khurram Shahzad Munawar, Saqib Ali and M. Nawaz Tahir


In the title compound, C11H10N2O5, the amide group is nearly coplanar and the ester group approximately perpendicular to the vinyl C—HC=CH—C group [dihedral angles of 5.0 (2) and 88.89 (5)°, respectively]. This results in a short intra­molecular O =C⋯O=C contact of 2.7201 (17) Å between the amide O atom and the ester carbonyl C atom. The prop-2-enamide fragment and the nitro group make dihedral angles of 20.42 (6) and 13.54 (17)°, respectively, with the benzene ring. An intra­molecular C—H⋯O inter­action between the benzene ring and the amide group generates an S(6) ring motif. Inter­molecular C—H⋯O and N—H⋯O hydrogen bonds complete R 2 2(11) ring motifs and join mol­ecules into [100] chains
