(E)-Ethyl 2-cyano-3-[5-nitro-2-(pyrrolidin-1-yl)phen-yl]acrylate.

ABSTRACT: The title compound, C(16)H(17)N(3)O(4), was prepared by the reaction of 5-nitro-2-(pyrrolidin-1-yl)benzaldehyde and ethyl cyano-acetate. The mol-ecular structure adopts an E conformation with respect to the C=C double bond. The five-membered ring has a half-chair conformation, with puckering parameters Q(2)= 0.399 (2) Å and ϕ = 93.1 (3)°. In the crystal, inversion dimers , linked by pairs of C-H⋯O inter-actions, are further connected through C-H⋯N hydrogen bonds. Weak slipped π-π inter-actions occur between symmetry-related benzene rings [centroid-centroid distance = 3.785 (1)Å].
