Ethyl 3-[7-(N-acetyl-4-meth­oxy­benzene­sulfonamido)-3-chloro-2H-indazol-2-yl]propionate

In the title compound, C₂₁H₂₂ClN₃O₆S, the fused five- and six-membered ring rings are almost perpendicular to the planes through the atoms forming the acetyl and the propionic ester groups, as indicated by the dihedral angles of 80.3 (2) and 88.3 (7)°, respectively. The dihedral angle between the indazole system and the 4-meth­oxy­benzene­sulfonyl group is 13.76 (6)°. The carbonyl O atom is split over two positions in a 0.60 (5):0.40 (5) ratio. In the crystal, mol­ecules are linked by C—H...O and C—H...N inter­actions into a three-dimensional network.

6,6′-Di­nitro-1,1′-(ethane-1,2-di­yl)di(1H-indazole)

The mol­ecule of the title compound, C₁₆H₁₂N₆O₄, is built up from two fused five- and six-membered rings linked by an ethyl­ene group. The dihedral angle between the planes through the indazole ring systems is 39.74 (5)°. The nitro groups are tilted by 7.2 (2) and 8.5 (2)° with respect to planes of the fused-ring systems. In the crystal, mol­ecules are linked by C—H...N and C—H...O hydrogen bonds into chains running parallel to the c axis.
