Abstract: The structures of 5-nitro-3-thiomorpholino-1H-indazole, C₁₁H₁₂N₄O₂S, (IIa), and 3-(4-methylpiperazino)-5-nitro-1H-indazole-methanol-water (2/1/1), 2C₁₂H₁₅N₅O₂·CH₃OH·H₂O, (IIIa), are described. In the crystal lattice of (IIa), the molecules are linked into dimers by N-HN hydrogen bonds. The asymmetric unit of (IIIa) contains two independent molecules of the indazole moiety, one molecule of methanol and one of water. The three components of (IIIa) are linked by hydrogen bonds to form double chains running along the x axis. [bold pi] -Stacking involving the indazole moieties occurs in both compounds.

Formula: C₁₁H₁₂N₄O₂S und 2C₁₂H₁₅N₅O₂·CH₄O·H₂O
