Ethyl 3-[6-(4-meth­oxy­benzene­sulfon­amido)-2H-indazol-2-yl]propano­ate monohydrate

In the title compound, C₁₉H₂₁N₃O₅S·H₂O, the central indazole system is essentially planar (r.m.s. deviation = 0.012 Å), while both the benzene ring and the mean plane defined by the non-H atoms of the ethyl propionic ester unit (r.m.s. deviation = 0.087 Å) are nearly perpendicular to the indazole plane, as indicated by the dihedral angles of 82.45 (8) and 75.62 (8)°, respectively. Consequently, the mol­ecule adopts a U-shaped geometry. In the crystal, the water mol­ecule, which is linked to the indazole system by a strong O—H...N hydrogen bond, is also involved in two additional N—H...O and O—H...O inter­actions, which link the organic mol­ecules into chains along the b-axis direction.

5,11-Ditosyl-5H,11H-dibenzo[b,f][1,5]diazo­cine-6,12-dione acetic acid hemisolvate

The mol­ecular structure of the title compound, C₂₈H₂₂N₂O₆S₂·0.5CH₃COOH, is built up from three fused rings, two six and one eight membered. The eight-membered ring shows a boat conformation and the dihedral angle between the two benzene groups attached thereto is 66.43 (11)°, resulting in a V-shaped geometry. Two tosyl substituents are bound to the N atoms. The planes through the tolyl rings are roughly perpendicular, as indicated by the dihedral angle of 82.44 (12)°. In the crystal, the mol­ecule and its inversion-related symmetry-equivalent are linked to the acetic acid solvent mol­ecule by non-classical O—H...O and C—H...O hydrogen bonds. Two half-occupied acetic acid solvent mol­ecules are disordered at the same site and linked by a center of symmetry.
