Diethyl 2-aminothiazole-4,5-dicarboxylate hemihydrate

D. E. Lynch and I. McClenaghan

Abstract: The structure of the title compound, C₉H₁₂N₂O₄S·0.5H₂O, comprises two thiazole molecules and one water molecule in the asymmetric unit. The two thiazoles associate via N-HN hydrogen-bonding interactions to form R₂²(8) graph-set dimers, while the other NH groups and water molecules construct a hydrogen-bonding network that involves three of the four ethyl ester carbonyl O atoms.
