摘要

The dimethylammonium chloride adduct hydrate of cyameluric acid was obtained by slow hydrolytic decomposition of cyameluric chloride C6N7Cl3 dissolved in N,N-dimethylformamide. Single crystals of C6N7H3O3 center dot H2N(CH3)(2)Cl center dot H2O have been obtained after evaporation of the solvent. The structure has been determined by single-crystal XRD (P 2(1/c), a = 6.0908(12), b = 22.710(5), c = 9.821(2) angstrom, beta = 105.63(3)degrees, V = 1308 .2(5) angstrom(3), Z = 4, T = 130 K). In the solid, only the all-keto tautomere of cyameluric acid occurs. The molecular entities are interconnected by an extensive hydrogen bonding network. Vibrational and thermal properties of the compound have been investigated.
