[Pyridyl amide ligands]While pyridyl amide ligands possess varied and versatile coordination properties with transition metal ions, they also display interesting hydrogen bonding characteristics. This report, along with its preceding companion report (Acta Cryst. 2006, E62, o3337), illustrates the importance of steric bulk in determining the type and extent of hydrogen bonding observed between pyridyl amide molecules. Hydrogen bonding in the less bulky 2-phenyl-N-(2-pyridylmethyl)acetamide gives rise to one-dimensional chains while hydrogen bonding in the more bulky 2,2,2-triphenyl-N-(2-pyridylmethyl)acetamide results in the formation of dimeric pairs.
