(E)-6-Bromo-3-{2-[2-(2-meth-oxy-benzyl-idene)hydrazin-yl]-1,3-thia-zol-4-yl}-2H-chromen-2-one.

ABSTRACT: In the title compound, C(20)H(14)BrN(3)O(3)S, 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 [maximum deviations = 0.029?(3) and 0.007?(3)?Å, respectively]. The chromene ring system is inclined at angles of 7.37?(12) and 13.90?(13)° with respect to the thia-zole and benzene rings, respectively, while the thia-zole ring makes a dihedral angle of 12.58?(15)° with the benzene ring. In the crystal, mol-ecules are connected by N-H?O hydrogen bonds, forming C(8) supra-molecular chains along the c axis.
