1-Methyl-4-nitro-1H-imidazole-2-carboxylic acid dihydrate

H.-Q. Wu, Z.-G. Liu and S. W. Ng

Abstract: The hydrolysis of ethyl 1-methyl-4-nitro-1H-imidazole-2-carboxylate leads to 1-methyl-4-nitro-1H-imidazol-2-carboxylic acid, which crystallizes as a dihydrate, C₅H₅N₃O₄·2H₂O. The planar organic entity is a flat molecule; the molecules are linked through the water molecules by hydrogen bonding into a three-dimensional network.
