title: Ethyl (2Z)-3-hy-droxy-3-(4-nitro-phen-yl)prop-2-enoate.
abstract: The title compound, C11H11NO5, is essentially planar, with an r.m.s. deviation of 0.06 Å. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, molecules are linked by two pairs of C-H⋯O hydrogen bonds, forming sheets, lying parallel to (101), which enclose R 4 (4)(26) ring motifs.
