In the solid state the dimeric form is not present; the 2-pyridones form a helical structure over hydrogen bonds. Some substituted 2-pyridones form the dimer in solid state, for example the 5-methyl-3-carbonitrile-2-pyridone. The determination of all these structures was done by X-ray crystallography. In the solid state the hydrogen is located ...
They show a lot if information about the chemical structures and what they might be used for etc, but very often nothing about where they come from and what they are made from. This chemical N-Methyl-2-pyrrolidone is a prime example where there is nothing give anywhere on the page how it is made or what from.
