Two diacetylene derivatives (1, 2) carrying amide groups were prepared in order to control their packing arrangements by intermolecular hydrogen bonds. 1, 6-Bis(4-acetamidomethylphenoxy)-2,4-hexadiyne 1 is a symmetric diamide, which showed no changes by annealing. p-N-acetyl(6-hydroxy-2,4-hexadiynenyloxy)benzylamine 2 with amide and alcohol groups showed photo and thermal reactivity. Compound 2 crystallized in the monoclinic P21/c space group with a = 17.9162(3) Å, b = 4.8646(2) Å, c = 16.106(3) Å, β = 105.19(1)°. The molecules stacked one-dimensionally along the b axis and the intermolecular hydrogen bonds of the amide groups ran along the stacking axis. The hydroxyl group in the other end of the structure of 2 was also involved in polymeric hydrogen bonds, which also appear to play an important role in the molecular arrangement.
