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—HO, O—HN, N—HO and C—HO hydrogen bonds into molecular tapes perforated by R44(38) rings: these tapes are connected by further C—HO hydrogen bonds into a three-dimensional network.
