<span><strong>Preparation and Structural Assessment of Cocrystal Solvates and Cocrystal Salts of 1,3,5-Triazine-2,4,6-triamine with alpha-Hydroxycarboxylic Acids</strong></span>

Abstract

Abstract:In the present research, three cocrystals containing 1,3,5-triazine-2,4,6-triamine (melamine, me) were synthesized and characterized. The robustness of the amine-acid supramolecular synthon is discussed in the stoichiometry of the cocrystals of (me)·(H2ga)·1/2H2O (I), (me)·(Hme + )·(Hma − )·DMSO·3H2O (II) and (Hme + )·(Hma − )·diox·2H2O (III). The abbreviated designations used are glycolic acid (H2ga), D,L-mandelic acid (H2ma), dimethyl formamide (DMF), dimethyl sulfoxide (DMSO) and 1,4-Dioxane (diox). All the crystalline materials have been characterized by 1 H-NMR, 13 C-NMR, IR, and X-ray diffraction. The supramolecular assembly of each cocrystal is also analyzed and discussed.
