Linear chains in the 1:1 complex of thiophene-2,5-dicarboxylic acid and 4,4'-bipyridine

X.-Z. Sun, M.-H. Zeng and B.-H. Ye

Abstract: In the crystal structure of the title complex, C₁₀H₈N₂·C₆H₄O₄S or bpy·tdc (bpy is 4,4'-bipyridine and tdc is thiophene-2,5-dicarboxylic acid), bpy and tdc form one-dimensional zigzag chains as a result of O-HN hydrogen bonds. These chains are further assembled into layers by van der Waals attractions, which are extended into a three-dimensional network by van der Waals and aromatic - stacking interactions.
