title: 1:1 Adduct of (S,S)-4-amino-3,5-bis(1-hydroxyethyl)-1,2,4-triazole with (S,S)-1,2-bis(2-hydroxypropionyl)hydrazine stabilized by eight hydrogen bonds.
abstract: The structure of the cocrystallized 1:1 adduct of (S,S)-4-amino-3,5-bis(1-hydroxyethyl)-1,2,4-triazole and (S,S)-1,2-bis(2-hydroxypropionyl)hydrazine, C6H12N4O2.C6H12N2O4, has tetragonal symmetry. All eight O- and N-bound H atoms are involved in intermolecular hydrogen bonds, resulting in infinite zigzag chains of the triazole molecules, with the hydrazine molecules filling the gaps between the chains and completing a three-dimensional hydrogen-bonded array.
