A Perforated Molecular Tape in the 1:1 Salt of 4,4'-Trimethylenedipyridine and 1,3,5-Benzenetricarboxylic acid

The 1:1 adduct formed between 4,4′-trimethylenedipyridine and 1,3,5-benzenetricarboxylic acid is a salt C₁₃H₁₅N₂⁺.C₉H₅O₆⁻. The components are linked by a combination of O—H...O, O—H...N, N—H...O and C—H...O hydrogen bonds into molecular tapes perforated by R⁴₄(38) rings: these tapes are connected by further C—H...O hydrogen bonds into a three-dimensional network.
