Abstract
The thieno[2,3-b]pyridine ring system of the title compound, C17H16N2O4S2, is essentially planar, the amino and carbonyl groups being nearly coplanar with the heterocyclic ring system. There are two N—H⋯O hydrogen-bonding interactions involving the same N—H donor set and two different acceptors, one in an intramolecular bond helping to fix the molecular geometry and the other defining a dimeric structure around the symmetry centre at (0, , ).
