✦ Synopsis
The title compound, C 13 H 13 NO 3 , crystallizes with two molecules in the asymmetric unit. The values of the relevant C-C, C C and C-N bond lengths indicate that the molecules exist in the enamine tautomeric form. In each molecule, the cyclohexene ring adopts a slightly distorted envelope conformation. Molecules are linked by intermolecular O-HÁ Á ÁO hydrogen bonds between carboxyl and C O groups. There is also an intramolecular N-HÁ Á ÁO hydrogen bond in each molecule. Related literature For related literature, see: Allen (2002); Strozhev & Lielbriedis (1990).
