title: Ethyl 3-[6-(4-meth-oxy-benzene-sulfon-amido)-2H-indazol-2-yl]propano-ate monohydrate.
abstract: In the title compound, C(19)H(21)N(3)O(5)S·H(2)O, 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 mol-ecule adopts a U-shaped geometry. In the crystal, the water mol-ecule, 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 inter-actions, which link the organic mol-ecules into chains along the b-axis direction.
