  ABSTRACT: The title compound, 2-pyridinecarboxamide, C6H6N2O, crystallize in the monoclinic system with space group P21/n (No14), Z = 4, and unit cell parameters a = 5.2074(1) , b = 7.1004(1) , c = 16.2531(3) , = 100.260(1)o. The crystal structure of the title compound, was reported previously from Weissenberg photographic data with R = 0.127. It has now been redetermined, providing a significant increase in the precision of the derived geometric parameters. The crystal packing is governed by N--HO hydrogen bond-type intermolecular interactions, forming infinite one-dimensional chains with graph-set notation C(4), R22(8) and R24(8).
