4-[(Z)-(2-Eth-oxy-4-oxochroman-3-yl-idene)methyl-amino]benzene-sulfonamide monohydrate.

ABSTRACT: In the mol-ecule of the title compound, C(18)H(18)N(2)O(5)S·H(2)O, the heterocyclic ring adopts a twisted conformation, while the aromatic rings are oriented at a dihedral angle of 45.46?(3)°. Intra-molecular C-H?O and N-H?O inter-actions result in the formations of planar five- and six-membered rings. In the crystal structure, N-H?O hydrogen bonds link the NH(2) and SO(2) groups through R(2) (2)(8) ring motifs, while C-H?O and N-H?O hydrogen bonds result in the formation of R(2) (1)(7) ring motifs. N-H?O and O-H?O hydrogen bonds link the uncoordinated water mol-ecules, forming a polymeric network. A weak C-H?? inter-action is also present.
