The asymmetric unit of the title compound, C10H9N3O2, contains two independent molecules linked by a C—HN hydrogen bond. Each molecule has a similar conformation, being built up from fused five- and six-membered rings, each linked to an ally and nitro group, respectively. The indazole ring system makes dihedral angles of 2.7 (2) and 2.2 (2)°, respectively, with the plane through the nitro group. The allyl group is nearly perpendicular to the indazole system, as indicated by the N—N—C—C torsion angles of −75.3 (2) and −82.2 (2)°, this being the most important difference between the conformations of the two molecules. In the crystal, molecules are linked by C—HO and π–π [inter-centroid distance = 3.6225 (8) Å] interactions to form a three-dimensional network.

In the title compound, C14H12ClN3O3S, the fused five- and six-membered rings are folded slightly along the common edge, forming a dihedral angle of 3.2 (1)°. The mean plane through the indazole system makes a dihedral angle of 30.75 (7)° with the distant benzene ring. In the crystal, N—HO hydrogen bonds link the molecules, forming a two-dimensional network parallel to (001).

In the title compound, C14H13N3O3S, the fused ring system is almost planar, the largest deviation from the mean plane being 0.023 (2) Å, and makes a dihedral angle of 47.92 (10)° with the benzene ring of the benzenesulfonamide moiety. In the crystal, molecules are connected through N—HO hydrogen bonds and weak C—HO contacts, forming a two-dimensional network which is parallel to (010).
