✦ Synopsis
The title molecule, C 6 H 8 N 2 S 4 , possesses a crystallographically imposed center of symmetry. The two ®ve-membered rings are in half-chair conformations. The crystal packing is stabilized mainly by van der Waals forces.

The title compound [alternatively called (__E__)-3-phenylprop-2-enal azine], C~18~H~16~N~2~, was synthesized by the reaction of hydrocinnamaldehyde with hydrazine hydrate. The nearly planar molecule is centrosymmetric, with the mid-point of the N—N bond lying at an inversion center.
In the molecule of the title compound, C 14 H 10 ClN 3 S 2 , the dithiolane ring adopts an envelope conformation. The intramolecular C-HÁ Á ÁCl hydrogen bond may be effective in the stabilization of the crystal structure.
A new method for the synthesis of aromatic poly(amino-maleimides) via polytransamidation followed by polyaddition and ring closure of 1,2-bis(3-carboxyacryloyl)hydrazine (BCAH) with aromatic diamines was found, using the processes between BCAH and anilines. Poly(aminomaleimides) were prepared either
