Abstract: The molecule of the title compound, C20H16N2O5S, is built up by one fused five-membered and two fused six-membered rings linked to ethoxycarbonyl and 3-nitrophenyl groups. The benzothienopyran ring system is nearly planar (r.m.s deviation = 0.0392 Å) and forms a dihedral angle of 86.90 (6)° with the aromatic ring of the nitrobenzene group. In the crystal, molecules are linked by N-HO hydrogen bonds and by - interactions between the phenyl ring and the six-membered heterocyle [intercentroid distance = 3.5819 (8) Å], forming a three-dimensional network.
