title: (Z)-3-(2-{2-[1-(4-Hy-droxy-phen-yl)ethyl-idene]hydrazin-1-yl}-1,3-thia-zol-4-yl)-2H-chromen-2-one.
abstract: In the title compound, C(20)H(15)N(3)O(3)S, an intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The chromene ring system is inclined at dihedral angles of 14.21 (9) and 9.91 (10)°, respectively, with respect to the thia-zole and benzene rings. The thia-zole ring makes a dihedral angle of 24.06 (11)° with the benzene ring. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into a zigzag chain along [20]. Weak N-H⋯O and C-H⋯O inter-actions connect the chains into a three-dimensional network. π-π stacking inter-actions with a centroid-centroid distance of 3.4209 (14) Å are also observed between the chains.
