The molecule of 2-(hydroxymethyl)-1,3-propanediol, C4H10O3, lies across a mirror plane in space group P2(1)/m, with disorder of both terminal hydroxyl H atoms. The molecules are linked by three O-H...O hydrogen bonds which combine to form sheets; in each O-H...O 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.
