Trimesic acid is a planar molecule (and is one of only four benzenecarboxylic acids with that property).[2]

Trimesic acid can be combined with para-hydroxypyridine to make a water-based gel, stable up to 95 °C.[3]

Trimesic acid crystallizes from water in a hydrogen-bonded hydrated network with wide unidimensional empty channels.[4]
