Crystal structure of diethyl 2-amino-6-[(thiophen-3-yl)ethynyl]azulene-1,3-dicarboxylate

The title compound, C22H19NO4S, has an almost planar geometry supported by intramolecular N—H...O and C—H...O hydrogen bonds. The thiophene ring is inclined to the azulene ring by 4.85 (16)°, while the ethoxycarbonyl groups are inclined to the azulene ring by 7.0 (2) and 5.7 (2)°. In the crystal, mo...
