【 摘 要 】

The hydro­chloride salt of isonicotinamide, C6H7N2O+·Cl−, has been synthesized from a dilute solution of hydro­chloric acid in aceto­nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydro­chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol­ecule and a chloride anion. An array of hydrogen-bonding inter­actions, including a peculiar bifurcated pyridinium–chloride inter­action, results in linear chains running almost perpendicularly in the [150] and [1-50] directions within the structure. A description of the hydrogen-bonding network and comparison with similar compounds are presented.
