The title co-crystal, C6H12N2·C6H6O2, is composed of neutral resorcinol and triethylenediamine molecules in which the resorcinol molecules came from the in situ decarboxylation of 2,4-dihydroxybenzoic acid. In the crystal, the components are connected by O-HN hydrogen bonds, forming a chain in the b-axis direction.
