(E,E,E)-1,6-Bis(4-chloro­phen­yl)hexa-1,3,5-triene

The title mol­ecule, C₁₈H₁₄Cl₂, lies about an inversion centre. The hexa­triene chain is planar with a maximum deviation of 0.0001 (17) Å. The torsion angle of the single bond between the chain and the benzene ring is -168.49 (17)°. In the crystal, the shortest inter­molecular distance between the Cl atoms is 4.0785 (11) Å.

5-Bromo-2-hy­droxy­benzaldehyde 4-ethyl­thio­semicarbazone

In the title Schiff base compound, C₁₀H₁₂BrN₃OS, the C-N-N-C torsion angle is 172.07 (11)°. An intra­molecular hydrogen bond exists between the hy­droxy H atom and the azomethine N atom. In the crystal, pairs of hydrogen bonds involving the imino H atom and the S atom give rise to supra­molecular dimers.
