Notes: The patterns of the NH stretching vibrations in the solid-state IR spectra of a series of 5-pyridylmethylenehydantoins revealed the presence of various modes of hydrogen bonding: intermolecular NH&4nldr; &4nldr;OC and intermolecular or intramolecular NH&4nldr; ‥‥N(py). These variations are related to the orientation of the pyridyl nitrogen and to stereochemistry. A distinction between intramolecularly and intermolecularly hydrogen-bonded compounds was also provided by comparison of the 1H NMR spectra in (CD3)2SO and in CDCl3.
