4-(5-Bromo-2-hydroxyphenyl)but-3-ene-2-one
The molecule of the title compound, C(10)H(9)BrO(2), a doubly conjugated unsaturated ketone, is almost planar (r.m.s. deviation of the non-H atoms = 0.039 Å). In the crystal structure, two mol-ecules are linked across a centre of inversion to form a hydrogen-bonded dimer by way of two O-H⋯O links.

The asymmetric unit of the title compound, C(14)H(11)BrN(2)O(2), contains two independent mol-ecules connected into a dimer by inter-molecular N-H⋯O hydrogen bonds involving the amine and carbonyl groups. The dimers are further connected by O-H⋯O hydrogen bonds, forming chains running parallel to the a axis, which are stabilized through π-π stacking inter-actions, with a centroid-centroid dista...

In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...
