Methyl 5-(4-hydroxyphenyl)-6-oxo-1,6-dihydropyrazine-2-carboxylate
The title compound, C12H10N2O4, is approximately planar, with dihedral angles of 5.53 (9) and 2.48 (13)°, respectively, between the benzene and pyrazine rings, and between the pyrazine ring and the methyl carboxylate plane. An intramolecular C—H...O hydrogen bond with an S(6) ring motif is observed....

| Summary: | The title compound, C12H10N2O4, is approximately planar, with dihedral angles of 5.53 (9) and 2.48 (13)°, respectively, between the benzene and pyrazine rings, and between the pyrazine ring and the methyl carboxylate plane. An intramolecular C—H...O hydrogen bond with an S(6) ring motif is observed. In the crystal, intermolecular O—H...O and N—H...O hydrogen bonds link molecules into a layer parallel to the ab plane. Adjacent layers interpenetrate each other through a π–π interaction [centroid–centroid distance of 3.4746 (11) Å]. |
