IUCrdata. 2021 Jun 4;6(Pt 6):x210555. doi: 10.1107/S2414314621005551. eCollection 2021 Jun.

Abstract

The title compound, C8H9NO3, likely generated through hydrolysis and esterification of 3'-carb-oxy-3-methyl-(1,4'-bipyridin)-1-ium chloride by ethanol, which contained water, has a nearly planar conformation. The crystal structure is sustained by one-dimensional chains along the a-axis direction based on bifurcated N-H⋯(O,O) hydrogen bonds between the NH group of the 4-oxo-1,4-di-hydro-pyridine ring and the two carbonyl O atoms.

Keywords: bifurcated hydrogen bonds; crystal structure.
