The trigonal symmetry of trimesic acid (1,3,5‐benzenetricarboxylic acid) [H 3 TMA] is exploited in the generation of honeycomb grid solids that eschew interpenetration. The structures of [N,N‐dicyclohexylammonium] 3 [TMA]· xMeOH and [N,N‐dimethylammonium] 12 [H 3 TMA] · [H 2 TMA − ] 3 · [HTMA 2− ] 3 ·[TMA 3− ] reveal, relative to H 3 TMA, expanded and contracted honeycomb grids having internal cavities with effective diameters of 12.7 and 10.4 Å, respectively.
