2-Amino-6-nitrobenzo-1,3-thiazole hydrate

D. E. Lynch

Abstract: The structure of the title compound, C₇H₅N₃O₂S·H₂O, comprises molecules of the thiazole in an extensive hydrogen-bonding network with lattice water molecules. The essentially planar thiazole forms centrosymmetric, hydrogen-bonded dimers via a pair of N-HN (HN 2.11  Å) associations. The second amino H atom hydrogen bonds to the water O atom, while the water associates to one nitro O atom and two other water molecules. Complexity in the hydrogen-bonding network arises because the water molecule is close to an inversion centre, thus producing an OwOw interaction.
