(Z)-3-(1-Hydroxy-3-oxobut-1-enyl)-6-nitro-2H-chromen-2-one
In the title compound, C(13)H(9)NO(6), the coumarin system has the benzene ring aligned at 0.61 (18)° with respect to the pyrone ring. An intramolecular O—H⋯O hydrogen bond stabilizes the molecular conformation and a C—H⋯O contact also occurs. In the crystal, weak C—H⋯O interactions link the mol...

| Sumario: | In the title compound, C(13)H(9)NO(6), the coumarin system has the benzene ring aligned at 0.61 (18)° with respect to the pyrone ring. An intramolecular O—H⋯O hydrogen bond stabilizes the molecular conformation and a C—H⋯O contact also occurs. In the crystal, weak C—H⋯O interactions link the molecules, forming inversion dimers. |
