Abstract

In the title compound, C19H13N3O3S·0.5H2O, both organic mol­ecules (A and B) exist in E configurations with respect to the acyclic C=N bond and have similar overall conformations. In mol­ecule A, the essentially planar thia­zole ring [maximum deviation = 0.010 (2) Å] is inclined at inter­planar angles of 11.44 (10) and 32.50 (12)°, with the 2H-chromene ring system and the benzene ring, respectively. The equivalent values for mol­ecule B are 0.002 (2) Å, 7.71 (9) and 12.51 (12)°. In the crystal structure, neighbouring mol­ecules are inter­connected into infinite layers lying parallel to (010) by O—H⋯O, O—H⋯N, N—H⋯O and C—H⋯O hydrogen bonds. Further stabilization of the crystal structure is provided by weak inter­molecular C—H⋯π and π–π [centroid–centroid distance = 3.6380 (19) Å] inter­actions.
