(E)-6-Bromo-3-{2-[2-(2-chloro-benzyl-idene)hydrazin-yl]thia-zol-5-yl}-2H-chromen-2-one dimethyl sulfoxide monosolvate.

ABSTRACT: In the title compound C(19)H(11)N(3)O(2)SClBr·C(2)H(6)OS, the mol-ecule adopts an E configuration about the central C=N double bond. The chromene ring system and the thia-zole ring are approximately planar, with maximum deviations of 0.027?(2) and 0.003?(1)?Å, respectively. The central thia-zole ring makes dihedral angles of 21.82?(9) and 5.88?(7)° with the chloro-substituted phenyl ring and the chromene ring, respectively. In the crystal, mol-ecules are connected via N-H?O, N-H?S and C-H?O hydrogen bonds, forming supra-molecular chains along the c axis. An intra-molecular C-H?O hydrogen bond occurs. ?-? inter-actions are observed between the thia-zole and phenyl rings [centroid-centroid distance = 3.6293?(10)?Å]. A short Br?Cl contact of 3.37?(6)?Å also occurs.
