Abstract: | The title compound (C7H6N4O5) crystallizes in the monoclinic space group P21/c with a=8.566(1) Å, b=14.493(3) Å, c=7.583(1) Å, β=87.75(1)°, V=940.7(3) Å3, Z=4, Dx=1.597 g.cm‐3. The structure was solved by direct methods and refined by full‐matrix least‐squares method (R=0.0696). The title compound consists of an imidazole ring with the two NO2 groups and one water molecule. The short inter‐ molecular N‐H…N 2.03(5) Å] and Owater‐H…O 1.98(5) Å] hydrogen bonds are highly effective in holding the molecule in a stable state as a whole. |
