Solvent-Controlled Rare Case of a Triple Helical Molecular Braid Assembled from Proton-Transferred Sebacic Acid

A novel triple helix based on proton-transferred sebacic acid was observed in a 1:1 organic salt of [(Hambtz)+(Hsba)−·2H2O] (1, ambtz = 2-amino-6-methoxybenzothiazole, H2sba = sebacic acid) incorporating a zigzag water chain. Changing the solvent system, another simple 1D zigzag chain, cocrystal [(ambtz)2(H2sba)] (2), was obtained. The structural dissimilarity between them was dependent on different conformations of ambtz and H2sba modulated by solvent systems. The photoluminescence behaviors of 1 and 2 were also discussed.
