چکیده
In the title compound, C10H8ClN3O2, the indazole ring system makes a dihedral angle of 7.9 (3)° with the plane through the nitro group. The allyl group is rotated out of the plane of the indazole ring system [N-N-C-C torsion angle = 104.28 (19)°]. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming zigzag chains propagating along the b-axis direction.

The 3-chloro-1H-indazole system in the title mol-ecule, C17H16ClN3O2S, is almost planar, with the largest deviation from the mean plane being 0.029 (2) Å for one of the N atoms. This system is nearly perpendicular to the allyl chain, as indicated by the C-C-N-N torsion angle of -90.1 (6)° between them. The allyl group is split into two fragments, the major component has a site occupancy of 0.57...

The mol-ecule of the title compound, C8H6ClN3O2, is built up from fused five- and six-membered rings connected to a chlorine atom and to nitro and methyl groups. The indazole system is essentially planar with the largest deviation from the mean plane being 0.007 (2) Å. No classical hydrogen bonds are observed in the structure. Two mol-ecules form a dimer organised by a symmetry centre via a clo...
