Hydrogen bonding in 2-(hydroxymethyl)-1,3-propanediol and N,N'-bis[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]malonamide

C. Fernandes, J. L. Wardell and J. M. S. Skakle

Abstract: The molecule of 2-(hydroxymethyl)-1,3-propanediol, C₄H₁₀O₃, lies across a mirror plane in space group P2₁/m, with disorder of both terminal hydroxyl H atoms. The molecules are linked by three O-HO hydrogen bonds which combine to form sheets; in each O-HO bond, the H atom resonates between the two O atoms. In the crystal structure of N,N'-bis[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]malonamide, C₁₁H₂₂N₂O₈, the molecule lies about a twofold axis and has four strong hydrogen bonds which form a mixture of chains and dimers; these combine to give a three-dimensional supramolecular framework.

Formula: C₄H₁₀O₃ and C₁₁H₂₂N₂O₈
