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-H...O hydrogen bonds and by [pi]-[pi] inter­actions between the phenyl ring and the six-membered heterocyle [inter­centroid distance = 3.5819 (8) Å], forming a three-dimensional network.
