Abstract: The asymmetric unit of the title compound, C₆H₅N₅·C₉H₆O₆, comprises a full molecule each of neutral trimesic acid (tma) and zwitterionic 5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetrazol-5-ide (ptz). The components are linked into a two-dimensional layer by a combination of O-HO, O-HN, N-HO and N-HN hydrogen bonds parallel to the (10) plane. Layers comprising alternating rows of tma and ptz are linked into a three-dimensional network by C-HO and - interactions between tma and tetrazolate rings [centroid-centroid distance = 3.763 (2) Å], and between pyridinium and tetrazolate rings [centroid-centroid distance = 3.745 (2) Å].
