(E)-Ethyl 2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)acrylate
The title compound, C(12)H(10)N(2)O(6), was synthesized via a Knoevenagel condensation and crystallized from ethanol. In the crystal, strong classical intermolecular O—H⋯O hydrogen bonds and weak C—H⋯N contacts link the molecules into ribbons extending along [010]. Intramolecular O—H⋯O and C—H⋯N...

description | The title compound, C(12)H(10)N(2)O(6), was synthesized via a Knoevenagel condensation and crystallized from ethanol. In the crystal, strong classical intermolecular O—H⋯O hydrogen bonds and weak C—H⋯N contacts link the molecules into ribbons extending along [010]. Intramolecular O—H⋯O and C—H⋯N contacts support the planar conformation of the molecules (mean deivation 0.0270 Å). |
