Two substituted 2-pyrrolin-5-ones: chains built from a single N-H...O hydrogen bond.
In each of methyl 2-methyl-5-oxo-2-pyrroline-3-carboxylate, C(7)H(9)NO(3), and 3-acetyl-2-methyl-2-pyrrolin-5-one, C(7)H(9)NO(2), the pyrrolinone ring is planar. In each structure, molecules are linked into simple chains by way of a single N-H...O hydrogen bond.
