Abstract

The title compound, diethyl (6-methyl-2-pyridyl)aminoethylenemalonate (1), crystallises in in the monoclinic space group P21/c (No.14). The unit cell parameters are a= 10.5657(7) Å, b= 9.1784(5) Å, c= 14.5681(7) Å, β= 101.636(6)°, Z’=1 and Z=4 at 150 K. The extended structure forms approximately orthogonal columns of stacked molecules. All bond lengths and angles are unremarkable. No disorder, twinning or co-crystallised solvent is present in the structure. An intramolecular hydrogen bond exists between the enamine nitrogen and carbonyl oxygen. Hirshfeld surface analysis reveals a short contact between a carbonyl oxygen and neighbouring aryl hydrogen, as well as a carbonyl-carbonyl interaction.
