T. Kolev, R. Wortmann, M. Spiteller, W. S. Sheldrick and M. Heller

Abstract: Molecules of syringaldehyde, C₉H₁₀O₄, are connected by intermolecular O-HO [HO = 2.05  Å and OO = 2.713  (2)  Å] hydrogen bonds between the 4-hydroxy and 1-aldehyde functions into infinite linear chains. The 4-hydroxy H atoms also participate in an intramolecular O-HO [HO = 2.22  Å and OO = 2.662  (2)  Å] interaction with a neighbouring methoxy O atom.
