N′-[1-(2,4-Dioxo-3,4-dihydro-2H-1-benzopyran-3-ylidene)ethyl]thiophene-2-carbohydrazide
The title compound, C(16)H(12)N(2)O(4)S, was obtained by the condensation of 3-acetyl-4-hy-droxy-coumarin with thien-2-ylcarbonyl hydrazide. The pyran ring adopts a 2,4-dione tautomeric form. The benzopyran ring system is almost coplanar with the thio-phene ring [dihedral angle 0.9 (2)°]. The exocyclic C=C double bond has an E geometry. The mol-ecular conformation is stabilized by an intra-mole...
